Textures appearing glossy despite being full roughness

Hi, I’ve been having this issue enough to make a post about it. First of all, I use 3D-Coat for texturing with the Unreal Engine preset, and then I throw those textures into UE4 onto models I made in Blender.

Okay, so the problem is that even for textures which have 100% or greater roughness and 0 metalness, they have this sheen from lighting within UE4 only. This is supposed to be cloth, therefore not reflecting light so much it drowns out its own color… This really makes it ugly for anything not metal.

This next one is from 3DCoat, with 0 changes at all, this is exactly what I export to UE4. Yes I know lighting can make a difference and trust me I’ve angled bright lights onto this, it only makes the tiniest slightest amount of reflection which I don’t get since it’s fully rough, but it’s barely visible unlike UE4.

I’ve unchecked SRGB on grayscale images and normals, only the albedo is using it. I haven’t seen any useful help for similar posts so figured I’d make my own. Thanks.

Just double check the metal and roughness (cause unreal likes to do crazy things when you bring it in for whatever reason), i’m sure you HAVE. Just wanted to mention it, because I’ve had things get changed by unreal.

Next up, check on putting specular at zero
And check your Ambient occlusion.

I some times get shine from these.

There is also a tick, that says “fully rough” inside the material when you have the make material atribues selected. I can usually get it to vanish playing with those things.
Some times it still just wants to shine though so i’m gonna watch your question and hopefully i learn more!

Literally just putting an add node connected to specular and making it 0 + 0 or 0 + 0.1 fixed it. Thanks.
