The data is already outside of Maya, I'm trying to bring it into Maya. When
you say "cache out to disk" I assume you mean in maya's pdc format? That's
not a bad idea, hadn't thought of doing it that way. Anything else would
have to be either imported and a particle system created/modified. Or, a
plugin, like the one I wrote for Molecules to the Max!, remember all those
molecular dynamics? ps the movies finished, they're working on the 3d
portion of it.
So far, this is my best attempt at keeping it simple
pShape = particle()
mel.eval('addAttr -ln "rgbPP" -dt vectorArray %s' % pShape[1].name())
mel.eval('addAttr -ln "rgbPP0" -dt vectorArray %s' % pShape[1].name())
# pos and color for each particle, lists are the same size
points = [ ... ]
colors = [ ... ]
emit(object=pShape[0].name(), pos=points)
for index, color in enumerate(colors):
particle(pShape[1].name(), edit=True, attribute='rgbPP', order=index,
vectorValue=color)
Again, this is extremely slow...
