VRayMtl differences

[paul_marshall]

Hello guys,
Whilst following some tutorials on where to plugin materials such as a Roughness map, I noticed that the slot names are different when I create a new VRayMtl. See the image.. the one on the left was imported from Quixel Bridge, and the slot is named Refl Rough but the new VRayMtl says Refl Gloss. I guess my question is, are they the same slot, or is there a difference and is it just a labelling error?
Many thanks.

It's not the same thing. If your material has a roughness map or a glossiness map you can choose the type in the vray material BDRF tab.

Ah right! That's great thank you very much. I forget about that setting.
