Send to Unreal - roughness texture imported to metallic slot, metallic texture not present #671

Closed redemprez closed 9 months ago

redemprez commented 9 months ago

I export an object from Blender 3.6.4 to Unreal 5.3.1 via SendtoUnreal 2.4.1 with material and four textures (base color, roughness, metallic and normal map). After import UE creates a material and binds the textures, but it does NOT import metallic texture at all and plugs roughness texture into metallic slot.

Hi yes, this just has to do with how blender's fbx exporter and unreal fbx importer support materials. The reccomended workflow is to author shaders in unreal. FBX can help you get the material assignment over to unreal but can't be relied on to support much more.

The scope of this tool is to handle these asset types: StaticMesh, SkeletalMesh, AnimSequence, Groom(Experimental). Hopefully that answers your question 👍
