how can i solve this problem

I had made an object in the blender (a wood log wall

) and it has exported very well. but this object having some problems importing in UE4

in the case of .fbx extension, it doesn’t import materials and texture.

But in the case of .obj extension, it does import materials and texture but the mesh is not well.

Did you check “import materials” when you tried importing the .fbx into Unreal? It gives you that option when the pop up menu appears.

I have found in obj file, mesh scale is 0.1% of original
