How you see on the image, I have weird different materials on the mesh (actually it is one material)
I made the mesh in Blender and the material is the same! But it dont looks like the same.
The material is the oak material from Starter Content.
I unwrapped the mesh in blender and I added a UV Project map in blender.
I dont know how to fix this…
Well it just means, that your UV’s are positioned differently than UV’s of all other meshes. Try to import the image you are using for material to Blender, and reposition UV’s so they correspond to the look you want.
