Re: [Nuke-users] Deep to position

[Hugo Léveillé]

Hey thanks, works great. But for some reasons, depth channel has some
holes in it when outputted from nuke's scanline renderer. with
overlapping geos. But good enought for what I need

[Nuke-users] Deep to position

[Hugo Léveillé]

Is there a quick way to generate a 2d position pass out of merged deep
layers. I have several deep layers that I combined together before
outputting to 2d and I would like to get the position pass of all those
layers. Could probably get this using the scanline render on a
deeptopoint but that would probably have quality loss

Yeah.. was hoping maybe something got developed with the ray render or someone

 The result is perceptually indistinguishable.

Re: [Nuke-users] auto-switch node

Something like this? Just add a checkbox to your input with an
expression to see if there is a connected node to that input. Then just
link your switch to that. Is this example, if there is something
connected to input 2, the internal switch will read it, else it reads
input 1

set cut_paste_input [stack 0]
version 10.0 v1
ColorBars {
 inputs 0
 name ColorBars1
 selected true
 xpos -185
 ypos -106
}
CheckerBoard2 {
 inputs 0
 name CheckerBoard1
 selected true
 xpos -330
 ypos -96
}
Group {
 inputs 2
 name Group1
 selected true
 xpos -243
 ypos 77
}
 Input {
  inputs 0
  name Input2
  xpos -153
  ypos -24
  number 1
  addUserKnob {20 User}
  addUserKnob {6 input_check +STARTLINE}
  input_check {{"\[exists input1.name]"}}
 }
 Input {
  inputs 0
  name Input1
  xpos -366

 }
 Switch {
  inputs 2

Re: [Nuke-users] JPG damage recreate

[Hugo Léveillé]

Genarts has a really cool jpeg damage filter that will do just that

You can also add grain to a grey constant and render it with low jpeg quality. 
Then put it in overlay. You will be able to fade the amount of compression you 
want to add without re-rendering the entire comp each time

[Nuke-users] Zync question for Nuke

[Hugo Léveillé]

Just tried Zync for the first time tonight. Worked well but I have a question. 
Starting instances take at least 5 minutes. 

So with that time, I don't see how it can be used to render several iterations 
rapidly. 

Is there something I am missing on how to make instances start more quickly or, 
is there a way to let instances run after a job is completed? Like letting 3-4 
instances running all the time. I'd be paying even while not rendering but at 
least, I could send several iterations in minutes interval

Here is a quick typed on iPhone version, it "should" work. Will get all

you just need to modify the code a bit

def build_templates(templates_location):
menu = nuke.menu("Nuke").addMenu("Nuke Templates")
for root, folder, files in os.walk(templates_location):
for f in files:
print root, f
name = os.path.splitext(f)[0]
menu.addCommand(name, 'nuke.nodePaste("%s/%s")' % (root , f))
 
build_templates("/Users/hugoleveille/.nuke/templates/")

Re: [Nuke-users] adding menu item to link to fold with nuke template scripts

[Hugo Léveillé]

Here is a quick example. Add this to your menu.py and change with your
desired folder location containing your .nk files
 
*import *os
*import *nuke
 

*def *build_templates(templates_location):
menu = nuke.menu("Nuke").addMenu("Nuke Templates")
*for *script *in *os.listdir(templates_location):
name = os.path.splitext(script)[]
menu.addCommand(name, 'nuke.nodePaste("%s/%s")' %
(templates_location , script))
 

build_templates("/Users/hugoleveille/.nuke/templates/")

Re: [Nuke-users] python question for adding the local cache path in the proxy path

[Hugo Léveillé]

If you really need to put it in the proxy path, a simple find / replace
would do it
 
local_root = "/localcacheFolder/"
path = "/Volumes/RAID/project/file.exr"






def set_proxy_path(node):
convert_path = node['file'].value().replace("/Volumes", "_Volumes")
proxy_path =  local_root + convert_path
node['proxy'].setValue(proxy_path)



node = nuke.selectedNode()

Re: [Nuke-users] Change Read-Path depending on Write-node?

[Hugo Léveillé]

There is multiple solution to this.

One would probably be the beforeRender callback where the write node
would modify the path of the read node. You could also save a .py
template with some placeholders and use the sys,argv to fill your
placeholders. So you would always use the same .py file but depending of
the argurment that you provide in the command line, Nuke would render to
your desired location without saving a script

But I would start with the beforeRender callback. Just put a simple
function that modify the path of the read.

Re: [Nuke-users] List All read nodes

[Hugo Léveillé]

GUI

To get the path:

for i in nuke.allNodes():    if "file" in i.knobs():    print
i.name(), i['file'].value()

To store the nodes in a python list


l = list() for i in nuke.allNodes():    if i.Class() in
["Read","Camera2","ReadGeo"]:    l.append(i)
Note: You can use this code in a non-gui session, just use the Nuke
  python interpreter with the import nuke statement




Non GUI script = "path/to/file.nk" open_file = open(script)

for line in open_file:    if line.startswith("file "):    print
line.replace("file ","")

Note: You could do something better with regular expressions, but this
  gives you the idea

Re: [Nuke-users] Tips for damaged footage

[Hugo Léveillé]

Hey

I don't think you can use this as a grain/regrain solution. But I might
be wrong. As I see it, the grain is not a frequency that goes crazy and
create an overall defect in the entire plate but an overall sensor
response that is baked in the image.

And adding grain node to a checkerboard will generate values everywhere

But I have seen some crazy thing in a image that I just could not
believe that could be removed without affecting a single detail.

Hey

I have made a tutorial on something like this a few weeks ago. I have
not seen your clip but maybe it could help. You need to use the FFT node
(fast fourier transform) to remove the problematic pattern. 

Like I said, it depends of the clip, but I'm pretty sure it can help

[Nuke-users] ACES primaries problem

[Hugo Léveillé]

Hey guys

I had to deal with exr files that were in ACES primaries. My experience with 
aces is somewhat limited so I just interpreted it as regular linear in-out. For 
the kind of work we had to do, it was good enough

The small thing I noticed is that when playing back the comp in RV, the file 
looked a bit different. By looking at the metadata, I noticed that Nuke trashed 
the primaries in the exr render so now rv was interpreting it wrong. I have to 
ignore the primaries interpretation in rv to have a plate and comp that looked 
the same in RV.

I know I am delivering the same thing that I received, but still, I am curious 
on how I can make the primaries info go all the way in the metadata of the comp 
exr. Do I have to switch Nuke in ACES lut mode or is there a way to do it in 
nuke's default config?

Thanks

[Nuke-users] 4k exr playback

[Hugo Léveillé]

Hey guys 

Anyone of you ever tested 4k 16 bits exr in zip1 in RV for realtime playback? 
We have a 1.4 gigabytes raid so the bandwidth is not the problem as we need 
something like 900MB.

But the CPU is dying when decompressing the frames. Before trying something 
else, anyone successfully played this in realtime in RV?

DPX is playing fine be we are trying to make a exr only workflow.

Hi Pat and Magno. regarding the #remove the line below caveat, if
you end the script with:

if __name__ == '__main__':
freezeWarp2()

#end code

then you don't have to worry about removing that line.

Re: [Nuke-users] splinewarp

[Hugo Léveillé]

Here is my original ticket number 201302041204

Then when I asked for an update and was told it was merged with
201302041204

Then we asked severa ltime for updates on those since Nuke 7.0

thanks

 Instead of going back to Nuke 6.3 you can use SplineWarp1 (the current
 version is SplineWarp3) with the command window (press the 'x' key in
 the DAG).

 But I can see that that would be annoying for TDs wanting to use
 SplineWarp3, so I'll add your comments and try and get the priority
 on it raised but you'll have to understand that the original
 developer for SplineWarp 3 left some time ago.  I have just looked at
 the history for those bugs and we have had a few requests to
 implement that feature just not enough to trigger us to implement it
 (weirdly none from Hugo or Vision Global, which is something we'll
 look into), but as I mentioned I'll try and get it escalated - no
 promises though :)

 Hi Pat and Magno. regarding the #remove the line below

you end the script with:

freezeWarp2()

then you don't have to worry about removing that line.

[Nuke-users] Read files in write not working

[Hugo Léveillé]

Hi

Is the Read files function in the write node supposed to work ? When I
render a precomp and use Read files and check files matches input,
it will work after a local render. But if I close and open the script
again, I get an error that the input does not match the tree

Re: [Nuke-users] drop deep samples

[Hugo Léveillé]

If you just put a simple sphere with antialiasing to high and that you use the 
deep sample, you'll see some random pixel sample with multiple samples right in 
the middle of the sphere. And if you use multisamples with a moving camera, 
then all samples are just crazy.

Do you have a exemple of that deep expression?

 Just ran a quick test and it appeared to do that automatically in Nuke 9.05 
 when using DeepToPoints post Scanline.
 
 There are hidden DeepDeOverlap, DeepOmit  Deep Clip Z nodes available after 
 updating that may try to do something you're after.

 If not, the workaround that has worked for me is to run an expression with 
 DeepExpression that pushes the location of any deep samples with zero alpha 
 behind the camera frustum, then use a DeepCrop to get rid of them. Hope 
 that helps.

[Nuke-users] Roto handle in nuke 7

[Hugo Léveillé]

Hey

Am I the only one to find the roto point selection in nuke 7 to be not
as good as Nuke 6 ?

I often find it impossible to draw 2 points very close together. Nuke
will try to select the point before instead of making a new one.  Also,
when selecting 2 points close to  each other, its almost impossible to
select 2 point and move them together. I often end up by modifying the
transform rectangle of the points instead of moving them together

I did not have those issues in Nuke 6

Re: [Nuke-users] How to add pyqt in nuke ,custom design ui and node

[Hugo Léveillé]

I suggest you use PySide instead of PyQt. PyQt under windows is
unusable in nuke. Many signals will crash nuke

Re: [Nuke-users] input format expression

[Hugo Léveillé]

For your exemple, a simple height/2 and width/2 would do it

Is it possible in an expression to use the input format? So for

Re: [Nuke-users] Hide knobs dynamically (like in the write node)

[Hugo Léveillé]

Hey

You don't need to run a callback from a menu/init.py. Just put the code
inside the node's knobChanged knob. So the code will be embeded in the
gizmo

b = nuke.createNode(Blur)
b['knobChanged'].setValue('''
k = nuke.thisKnob()
n = nuke.thisNode()
if k.name() == size:
if k.value()  25:
n['mix'].setVisible(False)
else:
n['mix'].setVisible(True)
''')

I made a gizmo that has a shitload of different settings, to clean that

Exactly like it works in the write-node when you pick file type.
I have written the code for the actual hiding/unhiding in python,
problem is I can't seem to figure out how to run the script when I
change the menu knob.

I scanned through the python guide and found the knobChanged callback,
but I can't really figure out how it works. Also I don't want to have
to run a callback every time I start nuke (or incorporate it in my
menu.py). As that makes the gizmo a pain in the ass if i want to share
it.

It also seems inefficient to constantly run a callback, just in case
the user might change some parameters of one node.

I also feel that there should be a way to hide/unhide knobs in a more
local way, through TCL or something.

Anyway, all help is greatly appreciated

Re: [Nuke-users] parent card to camera with half speed values

Yep

Or just make a flloating point slider and use that to drive the
expression instead of the number 2. Will be much quicker to change the
value

Yes, that's it. Seems simple really.
So the expression just divides whatever the translation is by 2?

Re: [Nuke-users] Gizmo don't save Axis file knob value

you can set it to hidden if you dont want the user to see it)

Re: [Nuke-users] OT - flock

[Hugo Léveillé]

Would it be possible to make the bunch of birds follow a 3D curve
created with the polygone plugin ? I did not find any ways to use the
CurveAttach node with Nuke's particles. Those birds would then be very
usefull :)

Duplicator from Nukepedia does the same for 3D (and of course, the

Re: [Nuke-users] Simulate bad streaming

The problem is that the video beeing played back for capture is no near
playing realtime on the other computer. It plays at 2-3 frames seconds
unlike a webcam that plays realtime but with temporal compression. I ll
try a quicktime with low compression and big keyframe separation

[3]http://www.nukepedia.com/gizmos/dynamics/
These builds are for 6.3 and 7.0b100.
There are more concise descriptions on the respective pages, but a
brief overview:
Geometry Tools; surprisingly, creates and modifies geometry:
  * Create 3D Text, 3D Shapes (from roto curves), Voronoi-shards, and
copy geometry onto points or with an accumulated transform.
  * 3D Curves that you can sweep, revolve, or create an axes on.
  * Boolean operations, face/edge extrusion, Catmull-Clark subdivision,
face removal/poking and point merging.
  * Test geometry for intersection with an ellipsoid, trapezoid, or
cylinder for:
modifying attributes with values or expressions, and applying
Transform, Bend, Bulge, Taper, and Twist deformers.

Dynamics; oddly enough, allows rigid and soft body simulations in Nuke.
  * Integration with particles to trigger emission when objects collide
or simulate geometry emitted from a stream.
  * Achieve realtime playback with a massive amount of objects (30,000
for example).
  * Simulate deforming geometry and concave objects.
  * Animatable properties and constraints (point, hinge, spring, soft
pin, soft to rigid).
  * Baking of both rigid and soft bodies (invokable in UI and
command-line).
  * Bake object transforms to Axis nodes.

Thanks, and let me know of any issues.

Re: [Nuke-users] Halt expressionlink?

[Hugo Léveillé]

You could try to put a callback on the noop to update your reads when
you update the noop. That would be a solution if your setup is
currently hanging your script

Hey,


We have a setup where all read-nodes get their filepath from one
Noop-node.

Have been working great for updating all CG in a shot at one place
instead of 50..

But now we have problems with a lot of lag in Nuke.. even if you’re
just looking at one node.. Feels like all the readnodes tries to read
their path all the time, is there a way to halt expressionlinks to a
noop-node from being active all the time? Or is it something else,
someone recognize this problem?


So what the expression does is basicly reading filepaths from a Noop,
nothing fancy. Just that there is like 50 reads or so.

  Hey everyone,

  This works:

a = nuke.toNode(SomeOtherCheckerboard)
f1 = a['format'].value()
#Get a format object using the .value() method of a format knob.
b= nuke.toNode(CheckerBoard)
b['format'].setValue(f1)
#Works fine.

  This fails:

a = nuke.toNode(Blur1)
f1 = a.format()
#Get a format object using the .format() method of a Blur node.
b= nuke.toNode(CheckerBoard)

[Nuke-users] Scanline bug

[Hugo Léveillé]

I sent this to support but they were not able to reproduce it. Anyone
experienced that?

===
We have a bug using the scanline render. We project a crowd on a card,
and when rendered, even with overscan set to ridiculous number, we loose
some info on the frame in the bbox

See script attached. If you look at the transform, you will sometime see
a guy appearing on and off at the right of the screen

Just to show you what happen on my screen, here is a quick screen grab.

You see, using the exact same script I sent you, how the projection cut
itself for no reason, and reappear when I change some knobs that have
nothing to do with the projection

A start would probably be to key the guy on the desired BG, then
add the flashlight using the screen blending mode on the
composite. Then it all depends if you need to track the flash
light on the candle or not.

There's shot of a guy walking in a forest holding a candle,
that's a greenscreen shot. Another shot is a effects guy shinning
a flash light to simulate the luminance value coming from the
candle. The effects guy is in a dark room shinning the flash
light. I'm not sure the best approach to merge these two shots.
I hope it's better now.

Re: [Nuke-users] Assigning hotkeys messing with createNode position

[Hugo Léveillé]

Looks like a bug to me. It is also doing that with a callback. So
the code above also does the problem

def hideInput():
nuke.thisNode()['hide_input'].setValue(True)
nuke.addOnUserCreate(hideInput,nodeClass = Blur)

I would report it

Sorry what I gave was just an example, not my actually code. I
knew that would cause problems, ha. Anyways as Woei pointed out
in a personal message, having 'shift' in a hotkey will
automatically break off the node from the tree. Thus putting it
off to the side. So it is using the shift key behaviour when I
use my hotkeys. Both of the hotkeys I had reassigned used the
shift key. So I was able to fix it by using 'alt' instead.
However the node I was redefining still spawned in odd locations
no matter what, and seems to be another issue entirely. if you
set the knob default of a node to have hide input on , then it
spawns the node in the top left corner. I tested these with
multiple nodes. That seems like a bug. but I don't know.
You could test this line, spawned the node in the corner with
every node I tested this on. Not sure if that is normal behavior.
nuke.knobDefault(Blur.hide_input,1)
For now I am fixing this issue by setting the node position based
off the selected node.

Re: [Nuke-users] Gizmo - Dynamic Properties Tab

[Hugo Léveillé]

hey

this should get you started. For this exemple, I just created a
Blur and added a slider to it so that the User tabs knob is
created. Then I seected the node and run this script in the
script editor

s = nuke.selectedNode()
s['knobChanged'].setValue('''
n = nuke.thisNode()
k = nuke.thisKnob()
if k.name() == inputChange:
if n.input(0):
n['User'].clearFlag(nuke.INVISIBLE)
else:
n['User'].setFlag(nuke.INVISIBLE)
''')

This will add a code to be run everytime the input of your node
is changed. So in this case, if the blur is connected to another
node, the tab will be shown. For a 2 input node, just change the
input number to match the one you need to track.

Hope this get you started

is possibile hide the second tab when the B input is not
plugged??..
i know...it's not a big problem...but i think that would be cool
have a dynamic properties tab for my gizmo!
thanks
regards

[Nuke-users] Plog viewer process

[Hugo Léveillé]

What would be the correct formula to generate a viewer process for log
plate converted using the PLog conversion ? Basicly, seeing the same
result in the viewer as if I converted the plate using the default
logLin but minus the negative value


Thanks

Re: [Nuke-users] Plog viewer process

[Hugo Léveillé]

Salut Vincent

This is not what I am looking for. The result on the screen is
the same as:

plate(raw input)== plog2lin == srgbViewerprocess

The difference is that with your viewer process, you have to look
directly at the plate in raw input (and the plate is then not
linearized).

What I am looking for is the color offset needed to show the
black on screen as if I converted using the default cineon, while
keeping the data in range under the hood. So what I am expecting
is to get same same result (visually) with this:

Plate  Log2ling  srgbViewerprocess
Plate  plog2lin  newViewerprocess

Anyone experienced a bug while setting keyframes ? Often, when I set a

Re: [Nuke-users] Nuke + linux

We use nuke under CentOS and recently tried Fedora. Nuke under
Fedora swapped ram alot and some artist complanined alot. Under
CentOS, its rock steady. You will still need some windows/osx to
generate QT since its very restrictive under linux.

We were trying fedora 15. Some users experienced hangings when
flipping large sequences (1000+frames).  And yes, copy / pasting

unusable). Under fedora its no problem.

Re: [Nuke-users] Customizing menu.py

[Hugo Léveillé]

You just need to make the file available on the network to
everyone. Then, add this line the the artist 's init.py local
file

import sys
sys.path.append('path/to/the menu/file/menu/py')


Nuke will load the menu.py once it pass it that path

You can also acheive the same thing with sys envirronement but
this should get you working

Hope this help

I would like to spread this file to all the workstation. Our in

I guess I should have Nuke, when launching, looking at the right
place to take on account this customized menu.py.



Any track I could try would be helpfull. Link, references,

[Nuke-users] Grade clamping

[Hugo Léveillé]

Is there a good reason why nuke's grade has the black clamp checked ?
More often than anything else, artist ends up destroying super black on
dark plates.

Am I missing something ?

 The mac32 problem is definitely bug 16283. It might be the same thing as

 Drop an email to support to raise the priority on it.

  Hi Wouter,
  Have you had a chance to look at this under Nuke 6.2.v1 32 bit on the
  Mac? It's the same there. Maybe this bug should also be logged under OSX?

Can you tell me what OS you are on (and whether 32 or 64 bit) and

version of 6.2 you are using?
   
It may be bug 16283.

 Hi

 Dialog box behaviours seems to have changed

 For ex:

 Select a read, and select Framecycler selected

 In 6.2, a dialog box will pop up to confirm framerange to flip.
  If you
 press ENTER right away, the flipbook start right away. But if
  you edit
 the range and press enter, the dialog close and nothing happen
  ( like a
 pressed cancel)

 in 6.1, even if I edit the range and press enter, the flipbook
  starts.
 This is very annoyong since I often edit the range with the
  numpad and
 press the enter key beside it

 Known bug ??
