    Uv overlap issue

    Hi
    I created a object. And I textured in substance. In UE4 when I always get uv overlap error. In that object I have so many uvs. so for same uv I used overlap way because I have same texture. But those uvs not overlap with different uvs. So how to resolve this error? Always when I click bake its dark and some kind of error. Please help me

    You need to unwrap your Object twice:
    One Unwrap (UV0) for Textures
    One Unwrap (UV1) for the Lightmaps.
    https://docs.unrealengine.com/latest...mapUnwrapping/

    For Lightmaps, you need to make sure your UVs do not overlap and everything is within the 0-1 UV Range.

      UV overlapping is fine for UV0, but you need to ensure none are overlapping in UV1 which as [MENTION=216469]Raildex_[/MENTION] mentioned is typically your lightmap channel. Once you've ensured no islands are overlapping you shouldn't receive an error or have dark objects.
