Maybe this is wishful thinking, but I’m wondering if I can utilize 2 separate UV layouts for a single Mix Material.
Here’s the scenario: imagine that I have map that’s segmented into several pieces; each piece is equal in length as it is in width, like a checkerboard, and each piece has it’s own 1024x1024 image texture instead of sharing one giant high resolution texture – so that being said, all the 3D pieces fit together to make a single image (like a mosaic, or a map). Now I’d like to have a second UV layout for each piece where they all fit together on a single image texture that’ll be used as a Mix Map.
The reason being is that I’d like to dynamically paint on a HTML canvas, use the canvas as the Mix Map texture and have all the 3D pieces update accordingly. I realize that I can avoid complicating the matter by just having a single UV layout where they all share the same diffuse texture that’s getting mixed, but by doing so I’m compromising image resolution significantly.
Looking forward to getting your thoughts, and thanks in advance!
