I finally sorted out RVT blending between my terrain mesh and rock mesh. Terrain material turned really green, in the shader complexity preview mode, after converting it to RVT stuff. The rock however remained brown as it was.
What do I need to do to make rock turn as green as the terrain ? Simply piping it into RVT output doesn’t do anything. Piping it into RVT output, then sampling from RVT and piping it into material output makes material green in the complexity preview, but material gets some super blurry gray spots (areas) on it.

EDIT: I did this and I got rock mesh to have lower compexity shader view, but it doesn’t look right at all:
Is it even possible to achieve!? If so, how?
P.S. For that last test I have 3 RVT volumes and each of the RVT meshes (terrain, rock) references all 3 RVTs (terrain, height and rock).
