Overlapping UV Question

I have solved the UV overlapping problem I was once happening. The only issue I am now having is understanding how to UV map without overlapping? For example if you look at this image:

If I wanted one of the faces of my wall to include the whole image I’d need to overlap the other UV layers wouldn’t I? And that causes problems in UE4 am I right?

Thanks

The overlapping UV error is just because of your lightmap. To solve it you will have to create a 2nd UV channel with a proper lightmap

I know how to add a lightmap, my question is how do I display that whole texture you see in the right UV viewer to one face of my walls without overlapping the other UV squares? If I over lap them to view the whole texture it won’t work will it?

Hi Nickmadd,

If you want the entirety of the texture to fit your mesh you will need to do one of two things. You can scale the texture down to fit the text within each one of the faces (the squares in your UV) or you can break the pieces to be individual faces within the UV space and fit the entirety of the 0,1 space. Since your first UV slot (the diffuse and other associate textures) can be wrapping this won’t give you an error if you create a second UV that holds your lightmap which you can find in the linked video that Fight5347 pointed you to.

If you need further assistance feel free to ask.

Thank you!
