SET UNITY DIFFUSE TEXTURE ON BLENDER FBX HELP!!

well i made a model, i even try to just make a simple cube with blender…i exported it in unity as a FBX…so now i want to apply a texture on my cube…a texture that was already in unity…a diffuse one…but when i set it on the blender fbx cube it is a kind of strange look like the texture is scaled!!! i watch tutorials…and all stuff but no one can solve my problem!!! HELP!

blender has no UV’s by default, you will need to UV unwrap your object to apply any textures.
As a side note, unity can load blend files directly without the need to export to fbx.
