This also happens if i resize a plainwall then apply the texture.
Hi Ghastly, I’m pretty new to the whole texture thing myself however i think what the issue here is (as i encountered this before as well) that textures are placed as is onto the static mesh. In this situation all i did was “split” the mesh (made more than one and lined them up).
I’m pretty sure there would be a way to create a blueprint which you would create using the texture, then in this blueprint you could modify the texture structure when placed on a static mesh. But im not yet proficient in blueprint yet
