How many UV cooridnate sets can be imported on a surface?

Unity Engine

Hi

I’m new to Unity so just getting to grips with it. One question that I need to know early in on in order to determine workflow is how many UV coordinate sets can be imported on a surface? I need one for diffuse texture, one for normal map, but I wonder if you cold also have one lightmap? That would be great!

Thanks in advance.

You can use 2 uv sets in Unity. In game development, it is very common that the same uv coordinates are used for the diffuse and the normal map. Like that it is possible to use the second one for the light maps.

Makes sense, thanks!
