Re: ICE Setting a Switch for Random Pairs?

[Bradley Gabe]

Incidentally, here's the logic construct for the solution. As it would
happen, it ended up being pretty darn simple.

Each particle was already storing the ID of its partner.
For each particle, I stored a unique random value in an attribute named
"priority".
The following tree sets the switch:

In house Softimage hair broken?

[Adam Sale]

Its been a while since I've tried the Softimage hair, but I find it so
ridiculously buggy, to be almost unusable in 2013.
My main issue is with the grooming. It seems like if I turn on render hairs
while styling the guides, after a few moves of tips, or whole strands, that
other sections of hair I've groome, suddenly pop into a different position,
or straighten...

What the?

Is anyone else experiencing this, and if so I hope its on the radar to
fix...

Granted, there are so many other hair solution out there today, but for
quick jobs like the one I needed today, I tried old school, and it bit me.

RE: ICE Setting a Switch for Random Pairs?

[Matt Lind]

Pseudo code:

Determine number of particles to be emitted
Initialize ICE attribute lookup table with flipped state status 
set to false for each index
Birth particles
Identify and assign IDs to particle pairs (odd/even pairs, for 
example)

For each particle in the cloud:
Particle does something to trigger event
Event code executes looking up particle's ID, 
paired particle ID, and ICE Attribute recording flipped status
If ICE attribute says particle 
states already flipped
Exit event
Else
Flip particle 
states
Record flipped 
status in ICE attribute
Exit event

Actually, I probably don't need to know.

Usually when you have this situation you need to involve a neutral 3rd party to 
manage the states.

One possible solution is to implement an event based trigger to look at the 
states of each particle in the pair and flip them if necessary.  This event 
would have to consult an ICE Attribute or some other external piece of data 
which records whether the particles have been modified before or not so the 
event doesn't accidentally get caught in a loop.  The name of the ICE attribute 
(or index in a table of some sort) could be stored in the particles.

RE: Polygon Island orientation

[Matt Lind]

If you're using polygon islands, then you're essentially doing deformations on 
a single mesh.  In which case the centers will not maintain alignment with each 
island because what you're seeing are not the centers of the islands, but 
temporary manipulators.  This is normal and expected behavior.

Your best option is to split each polygon island into it's own object so you 
can control them independently as objects.

If you insist on keeping them as polygon islands, a simple solution would be to 
create nulls to act as the centers of the polygon islands and assign the 
polygon islands to the nulls via an envelope.  You can then weight each vertex 
of each island 100% to it's assigned null.  Your ICE Tree would then push the 
nulls around and the islands would simply tag along for the ride.

Subject: Polygon Island orientation

Is there any way to change a polygon island's center axis without moving the 
points on the attached instances?

In the original geo, the points are oriented properly as are the original 
center points are pointing where I needed them, but since I am now using ICE to 
push them around, the particle points that are generated from the merged geo 
that the poly islands come from all orient global 0,0,0. Which was fine up 
until I was asked to constrain their orientation so that they Y axis is always 
pointed at the surface underneath.

So they need to orient flat along the surface, like how they start out in 
example 1, example 2 shows what's happening as they fly away from the surface, 
their orientation does not stay flat. In example 3 you can see what happens 
when I orient the axis towards the globe's surface, they all flip.

So I am a little stuck. After digging into the nodes I haven't found a place 
where I can make any changes to the orientation of the axis without the 
instances also flipping.

Thoughts?

Thanks,

Eric

though spot to be in... so there is a pointcloud controling all this

Im having a hard time trying to understand what is going on. The

So you might want to get the ofsset between that and the sphere and apply

RE: Small Annoying Things

[Eric Cosky]

If you have two RT shaders with different extensions, you can't distinguish
between them in the render tree shader list.

 

Ie

 

MyShader.cgfx

MyShader.fx

 

Show up in the list as:

 

MyShader

MyShader

 

Mildly annoying is how when the Realtime/CgFX category is selected, shows
both .cgfx and .fx files. Maybe I've got the wrong idea about what the .fx
extension is for but I didn't think .cgfx files would typically refer to .fx
files, I have always thought of .fx as being a DirectX/HLSL thing.  Perhaps
it would be helpful to have a new Fx subcategory adjacent to CgFX & HLSL.

 

A minor bug that would be nice to see fixed is if you use a dual display
setup with a custom view showing the rendertree in an embedded frame, if you
add a shader to the filesystem and hit refresh shaders button it doesn't
actually refresh the display - you have to hit the refresh shaders button in
a floating window for it to actually update the list. 

 

Finally, It would be really nice if the shader list didn't flatten out the
folder structure where it found the shader files. 

 

Thanks

 

 

Re: Polygon Island orientation

[Eric Lampi]

Yes, I believe so. I'm freelancing someplace and it was a tool they were
already using. I asked and I couldn't get confirmation, basically "I am not
sure where we got it". So it's made my job a little harder! It's "create
polygon island transform with and ICE pcloud" under the create>poly menu.

Re: Polygon Island orientation

I have one object with many islands, and yes, I want to orient the particle
points without moving the geo point positions of the instanced islands.

Re: Polygon Island orientation

[Alan Fregtman]

Polygon islands don't have real centers. I assume you meant you have
several objects, one per island and you wish to orient those without
touching the existing point positions? Am I right?

RE: Polygon Island orientation

[Grahame Fuller]

Maybe use two point clouds - one with the original orientation for the 
instances and a matching cloud with the particles' Y axes pointing at the 
surface. Use Switch Context to match their positions.

Subject: Polygon Island orientation

Is there any way to change a polygon island's center axis without moving the 
points on the attached instances?

In the original geo, the points are oriented properly as are the original 
center points are pointing where I needed them, but since I am now using ICE to 
push them around, the particle points that are generated from the merged geo 
that the poly islands come from all orient global 0,0,0. Which was fine up 
until I was asked to constrain their orientation so that they Y axis is always 
pointed at the surface underneath.

So they need to orient flat along the surface, like how they start out in 
example 1, example 2 shows what's happening as they fly away from the surface, 
their orientation does not stay flat. In example 3 you can see what happens 
when I orient the axis towards the globe's surface, they all flip.

So I am a little stuck. After digging into the nodes I haven't found a place 
where I can make any changes to the orientation of the axis without the 
instances also flipping.

Thoughts?

Thanks,

Eric
