[SOLVED] ShaderFX - Stingray Viewport PBS Not Rendering Correctly

For a while now I've been trying to figure out a way to get a PBR shader working inside my Max viewport. Whenever I use the ShaderFX Stingray shader however, my roughness map always becomes splotchy and pixelated.

 I've read that the stingray shader doesn't support grayscale roughness maps so I've went with the ORM (Occlusion, Roughness, Metallic) packed map approach but I'm still getting similar results. All my maps are set to linear encoding, and my gamma/lut is turned off in the viewport. Is this even fixable?

What is causing my roughness map to be rendered this way, and how can I remedy this?
