I’ve downloaded a mesh from the below link and when I import it to UE from Blender, the areas that should be sunken are raised. Basically, the scars look like scabs. I’ve tracked the behavior to the normal map, but I don’t know how to correct it. Inverting the normals altogether doesn’t fix the issue. See the images and link below; any help would be appreciated. Thank you.
Correct way in Blender:
Incorrect way in UE:
Hi, did you try to flip the green channel in the normal map? You can select that in unreal engine in the editor when you open up the normal map. AFAIK unreal engines needs the green channel to be flipped compared to blender, if you don’t do that the normal map ends up looking inverted.
I actually just found an option to let UE invert normals on import, which did the trick (see below). I wasn’t aware of the green channel issue though; so, I did test out your solution, using Gimp to isolate the channels. It worked as well. Looks as though I’ll want to look closer at my other imported meshes now. Thank you.
