Hi.

I have a particle sim and I want to assign various words to each of the points in the particles. I have one word instanced and it works, but how do I feed it a number of words (font nodes) and for it to randomly pick from ?

Thanks

Eugene

There are a couple of ways

1) Using geometry shaders
- Create a “Mantra: Delayed Load” shader (SHOPs)
- Use a material SOP to apply that material to the points (not primitives which is default)
- Use the material overrides to change the file

2) Use the “instance” attribute on points
See the “Particle” tab of the point SOP

See attached.

thanks… this will work with 3D text created in Houdini , rather than a texture ?

The example uses 3D geometry created in Houdini :-)

You need to gunzip the file first. Not sure what OS you're using but 7zip should do the trick.

Cheers!

I've attached the unzipped file.

If you want, you can try it in the Terminal.
gunzip points.hip.gz

Cheers!
