Quote - I don't have a good solution to the UV stretch problem and it is certainly the case that if you're using a UV-based shader, going too far in shape changes will harm it. Which is why I tend to use 100% procedurals.

I know. I was just teasing. :P But seriously:

Quote - [...] XYZ coordinate stretch problems that can mess up a procedural shader.

This has probably been covered elsewhere - I seem to remember a discussion somewhere of which nodes used UV coordinates and which didn't - but I wouldn't mind having my memory refreshed. Starting with: what are these XYZ coordinate stretch problems, and how do they mess up procedural shaders?

Quote - I can't remember if I published the morphing version or a fixed glass.

BBWineGlassWIP3 is fixed - no morphs, but a fine vintage all the same.

Since you mentioned procedural geometry earlier on, I was wondering if this might lead to a way to make an effective "drink" morph for a complex shaped glass, i.e. one without parallel sides. There are mathematical methods available to slave linear morphs together, and if these could somehow be matched up to the shape of the vessel things could get quite interesting. Forgive the flight of fancy.
