Re: -Camera. Frames issues

[Stephen Davidson]

Actually,  TV is 30 fps.,  or more accurately 29.97 fps,  but for short
clips 30 fps is fine.

 BUT... YouTube will play back up to 60 fps. Here is the info about

@Stephen, i read your words, thank you! Your info save my ass for future
projects. For now they told me they'll use this on TV and some documentary,
so 24fps. but my issue will continue then. I can't render with Arnold that
thing, i already have all animated. Maybe it's some feature for the

No, it does not, but you can't use field rendering on YouTube, anyway. See
my last post about
rendering 60 fps since YouTube will take that frame rate.

Re: scripting Weights

[Martin]

Thanks Alok, that's more or less what I'm doing. I have my weights array with 
rounded numbers but when I put them back to the envelope, they get converted 
into floating point approximations.

In Maya, the rounded weights get stored in the ma file, I'm not sure how Maya 
deal with that internally though, I'm guessing it's similar.

Re: scripting Weights

[Martin Yara]

I see, so it isn't possible.
Sometimes our clients ask us to round the weights to certain digits.

So far they've never complained when I used this old tool (that I was
trying to update), so I guess this should be good enough then.

Thanks.

Re: scripting Weights

[Luc-Eric Rousseau]

0.3 can't be expressed exactly in floating point numbers.
It's possible through manipulation that you can get it to a number
that the code that the function which prints the number happens to
neatly truncate back 0.3, but the value isn't actually ever stored as
0.3.

http://www.exploringbinary.com/floating-point-converter/
Select Single Precision. which is what the weight maps use.

The sliders in XSI just convert the number to text and then truncates
at a fix number of decimal, hiding the issue from you/

Re: ICE - how to align instances to edges?

[Olivier Jeannel]

Try rebuild the attached Icetree on the polymesh (Maybe some "build array
from set" problem ?)

Re: ICE - how to align instances to edges?

I tried rebuilding it in Soft 2013 SP1 (by copy/paste) as I might have to do
this in that version, but the Gg node remains red - is that a 2015 node?

Re: ICE - how to align instances to edges?

[Olivier Jeannel]

"Gg" sorry for the name ^^.
Look into the icetree that is on the "Grid" object. That's the one that
calculate the "tangent" I called "Gg".

To select all edges border :
Select edge mode (right menu)
then select "border edge" in the menu just below.
Now if you rectangle select with the mouse in the view, only the border
edges (the light blue one) will be selected.

Wow thanks a lot Olivier - that looks like it will do the trick. The reason
I didn't want to use curves is merely that I will get a lot of polygon
islands and don't know how to automagically select all border edges for
extraction - otherwise curve tangency would be fine.

The Get Gg node just before Align Particle to Vector looks like it is the

Re: ICE - how to align instances to edges?

[Morten Bartholdy]

Wow thanks a lot Olivier - that looks like it will do the trick. The reason I
didn't want to use curves is merely that I will get a lot of polygon islands and
don't know how to automagically select all border edges for extraction -
otherwise curve tangency would be fine.

The Get Gg node just before Align Particle to Vector looks like it is the one
that provides the edge vector, correct!? But I fail to understand what it is
doing though.

 selected and extracted, plus it seems the instances seem to be flipped
 180 deg
 on the y-axis between isntances without any way to control it.

 I have attached a screenshot showing a simple test where the A example
 is what I
 need, and B is what I get with Generate instance on Curve.

 Any ideas on this will be much appreciated.

Re: ICE - how to align instances to edges?

[Olivier Jeannel]

If you don't want to use curve (and curve tangent), I made this, but you
need then to subdivide your edges to get good result.
It calculate a "tangent" stored per point on the polygonal object.
Then your Pointcloud get the closest location and take that tangent data
and aligns vector.

You don't want to work with extracted edge curves ?
