i isolated the element 4 and as you can see object’s uv is on the model.
but when i opened the element 4’s material, textures doestn’t match with object’s uvs
I solved it. All the problem is the uv on the second image. It was for lightmap, that’s why it doesnt match with the images. The real uv is unpacked and as you can see most of object’s uv is not in the frame, probebly they wanted those separeted.
You mean the red lines representing most of the object’s UV? Those extend past the 0-1 space of the map (aka frame). If it’s a lightmap, it’s commonly said that the UVs are wrapping and that doesn’t work for rendering correct lighting. If it’s a texture map, it’s also commonly said that the UVs are ‘wrapping’, and is ok for texture maps.
