First of all excuse me for my English. I have a problem with a texture, I’m still quite new, I hope you can see what I mean on the picture. HERE

What happens if you put that texture on a plain cube?

Then looks good HERE

Ok, and can you show the UVs of the mesh?

I dont find this option in UE5…

It will be there, but I don’t have 5 at the moment, so I can’t show you…

I think your UVs may be screwed…

I found it

Hmm, they look ok.

These seams are your UV

But I’m not sure about the black lines. Can you show the normal map?

11

How do I get these individual textures, in the meshes or UV what ever ?

What is that? It’s so small I can’t see it :slight_smile:

13

That is apparently the Texture i need. Looks like the UV

14

The material on the mesh, will have a base color and a normal, probably. Maybe the black lines are in the normal map.

Ok, then I think it’s the mesh. What does it look like in this mode?

Yes, if you like. Put it somewhere I can download.

Ok, a big problem, is this is UV 1

But that’s the UV that UE uses for the lightmap. The engine uses UV0 for mapping textures, but your UV0 looks like this:

That’s why it looks shonky.

You need to make UV0 the same as UV1, that will help a lot.

21

and how switch the uv1 to uv0?

In the modelling software. I might be possible in UE, but I have no idea how…
