Instancing: Different noise for each instance

General TouchDesigner Discussion

Hi friends,

I’m sure this has been addressed but I can’t find an example. I would like animate some instances with noise, but for each instance to have a different seed, or translation value. My intuition says this is a GLSL approach?

I’ve attached a .toe to demonstrate.

Thanks for your help :slight_smile:

You could do this via glsl but maybe another approach would be Height Mapping which is available if you specify a Normal Map via a Phong MAT. You wouldn’t use Instancing for this at all but duplicate the initial geometry with a Copy SOP. There are no expensive SOPs as the deformation is done in the Material.

Cheers

Thank you very much that’s an excellent solution.
