If you’re using Render to Texture and it’s set to automatically unwrap the UVs on an uv channel different from the standard one, you will see the right texture with wrong UVs in Unity. Make sure you’re unwrapping on the first UVs channel if you want to use that texture as a Color texture. If you’re after lightmaps, then you will need two UV channels: one for the color map, and one for the lightmap.
