Landscape 5.5.1 RVT Roughness/Spec not working

Hello!
I’m using Brushify- Landscape material, the creator of the material is not responding to my request for help, so I’m asking you to see if you know what’s causing the problem.
UE 5.5.1

I need to use the RVT for optimization purposes , and I have a “puddle” layer that I am painting, but it doesn’t work when I use the RVT.
Does it not work for anyone else or is there something wrong with me ?
I understand that RVT should support Roughness and Specular maps…

Hi, did you check that the landscape material is setup to support this? So that it writes the roughness (and specular) value into the RVT and then read the roughness (and specular) value from the RVT? If not, you would need to modify the landscape material to support this.
