I was using rock models that were supposed to be desert themes as said in the name of the model but they have this white stuff all over them which doesn't really belong there.

Is this how they are supposed to look? I tried adding a weather grime volume but that is normally a red texture so I doubt that is the problem.

That is a weather grime issue I think... If that's a radiant screenshot thats how weather grimes show up in radiant I think

Really? Thought weather grime was fine in radiant and only showed up as red in-game.

Anyways, ill try to see if that is really the issue.
