Re: hide an instance by particle ID
Should work I guess. I prefer the Point shape though; it's lighter.

Re: hide an instance by particle ID
How would it react to having the shape set as an empty polymesh? I know it
used to insta-kill mental ray if you tried doing that, but is that still
the case now we have the Empty Poly Mesh as an actual 'thing'?

Re: hide an instance by particle ID
Happy to help! :)
If you want to restore the instance shape after, you could technically get
self.Shape and set it to a custom attribute when you're setting your
instance shapes, say self.OriginalShape, then when you wanna switch back to
the instanceshape, read that custom attribute and set self.Shape with its
data.

Re: hide an instance by particle ID
that with a string and string array, worked perfectly.

You could set their self.Shape to "Point" by testing their indices and they
won't render (without a pointcloud renderer/shader.)

hide an instance by particle ID
i have a particle cloud with geo instances attatched to them...
in some cases, i need to "hide" the instances and replace them with actual
geometry.
normally, i would just delete these associated particles by ID, however, i
still need the particles to generate pose information for the practicle geo and
"constrain" them ("transform objects by particle") to the generated particles.
alternatively, i could plot the animation, then delete the particle, but i want
to keep it all live.
is there anyway to selectively hide instanced geometry by ID?
thanks all,
john
