I have been trying to solve UV mapping issue since 15+ hours and I am about to lose my mind. What I want to ask you guys I have overlapping %2 and when I compile shaders and play it doesn’t look bad. If I leave as it is would I get any issue later? I want to leave it as it is because object is not looking different. When I had different UV error I dont remamber what was it. Object was completly faded. It turned out black. Would I have same issue again with % overlapping issues?
It means you have overlapping UVs in your mesh’s lightmap channel, if you try to do a lightmass bake, the lighting will be messed up in the areas that are overlapping. If you’re not baking lighting then it won’t matter (probably?)
If you can’t see it, it doesn’t matter
