[Feature request] FBX specular color import (+PATCH)

Is it a good idea to automatically assign a specular value to each unreal materials in which its FBX material has a specular color assigned to it? I have a bunch of materials imported from the FBX and there are lot of materials that shouldn’t shine (specular of 0, which is a property specified on each materials inside the FBX), so manually assigning a specular value to 400+ unreal materials takes a lot of time.

I just made a diff patch (UE4 master branch) to assign a specular value for an unreal material if its FBX material specifies a specular value, it’s up to the UE4 team to decide whether or not it should be featured.

While it sounds interesting, specular is barely used in ue4… only for very specific situations.
Roughness is the important value in ue4.

Unfortunately, roughness doesn’t fix my issue.

Here is a comparison :

The third image is what fits my temporary need.

EDIT : I just have tried with a roughness of 1 and higher, and it looks like it helps but the material is still shinning especially where it shouldn’t, like on stone walls.

well, thats what you get for not using a proper roughness texture, nor a proper albedo texture instead of diffuse.
