UV layout diffrent once imported

basically i go from Zbush - blender (where I set up my UVs) - substance painter 2 (where I bake my normals high to low) and then to UE4

but once I import my mesh to UE4 the UV textures are in a different location to what has been baked, i have done this before and it has never happened so I don’t understand, it most likely simple fix



bender UVs


Check that you do not have multiple UV channels and that you are looking at the correct on in Blender, Substance, and UE4.

I have looked at that, I only have the one, if there was a problem with the baking, wouldn’t it show up in Substance printer?
