How do they interact with each other? I decided to make it like this: If MultiOpacity is connected, the opacity will be read from this attribute, otherwise the…
Interesting, and works pretty well. Is this simply a reflection or some form of material capture (MatCap)? I guess at some level, that's probably the same. If the example Botz tiles are consistent enough, you might be able to get a proper MatCap of it by approximating a 3D model of the tile. Or maybe the edge regions are…
