Hi, I know it seems like this was asked multiple times but my google fu has failled time and time again and led me to similar questions but not quite what I wanted :mrgreen:
Does Unity support multiple UVs on the same mesh? By this I mean having an object with 2 UV maps. I’m having issues making it work properly.
Unity support 2 UV maps but the second is usually dedicated to lightmaps. If you don’t need lightmaps then you can make a shader that use the second uv for something else.
I’m having strange issues as it seems the second UV map isn’t being used for one of my materials. Should I just try to recycle the same UV for different textures then? It sounds a bit counter-intuitive but I must admit I’m still fairly new to UV mapping.
EDIT: ah I see, you’re only supposed to use one at a time right? I thought I could use multiple UV maps for parts of the mesh I wanted to unwrap onto a different texture.
This is a misunderstanding. You can just have two UV maps at one material. But you can have multiple materials at one mesh. Exporting a character with an extra texture for shoes, body and head works fine.
But beware, one material means one drawcall.
I see. Thanks. Am I right to assume then that having multiple UV maps for the object doesn’t mean anything when exporting for Unity?
It’s a bit weird as UV mapping on blender bunches up all the faces, even if they have different materials or textures, and I have to select them all manually. Am I missing something?
