I'm working through the “Writing a VEX Shader for Houdini” tutorial written by Andy Nicholas. In the tutorial, he demonstrates how to drive a shader with an attribute. I created a geo node at the object level, jumped in, and created several spheres. I used an attribute called “wrap” to drive the shader and assigned a different value to this attribute for each sphere.
The spheres were then merged. When I rendered the spheres, they looked the same! However, when I render each sphere separately, they look different, which is the effect I was going for.
One solution to this conundrum is to create separate spheres at the object level. However, I was wondering if I can achieve the effect I want at the geometry level.
