I have searched many different terms and phrases to try to learn a way to create the effect of the thermotropic liquid crystal paint (kind of like a mood ring) which is similar to a heat map. I can't seem to find much about it. It doesn't seem like that's a question here, either. Does anyone know how I could:
- Make a procedural material of this effect?
- Make only certain areas show the heat map like effect and leave the rest a dark color, if that's possible? (Similar to how it looks when you touch only a part of a surface painted with thermotropic liquid crystals.) I assume I would mask it out, but how?
I'm using Blender 2.92 on Windows 10.
