Hello! New here, but definitely not to mapping. I've been mapping for over a decade at this point. I recently returned to Source engine after a long time in UE and it's been well...challenging. One of the issues I'm facing is with Lightmapped4way materials for displacements. There's this strange error where, if a displacement is viewed at a certain angle, the fourth texture (ALWAYS the fourth) gets very dark, and turns either brown or a muddy blue. There also looks to be some other texture mapped onto it, I sometimes see striations. I've checked the .vmt and couldn't find anything off about it.[Blocked Image: https://i.imgur.com/ubMUIXP.jpg]

As you can see, the problem is pretty glaring.
Here is my vmt:

Any help is greatly appreciated. I'll definitely stick around and help whoever I can with their issues. Cheers!
