Well, it's in the quixel page tutorial and that's what the tutorial's author directed us to pick. Unless the "Metal Grime" was a custom preset of the author who made that video tutorial ... that may explain why the presets that came with Quixel default set didn't have it.
Don't know if the old dynamask is still in the 2.2.0 package since I joined the wagon late. Basically I tried to follow the tutorial - Petrol and at time 10:51 the tutorial was applying a dynamask called "Metal Grime". I cannot locate that dynamask on my version 2.2.0 Quixel has it been removed? Or did the installation…
