Problem using Raise or Lower terrain & Terrain Tools
Hi, I'm having a problem using the terrain tools system. Everything has worked ok so far. I use Unity 2019.3.13, I tried all restarting, reinstalling, create a new project but the problem is still here. I also tried updating to Unity 2020.2. I used both 2019.3 / 2020.2 versions of Unity for couple of projects but it worked fine in the past.
So it seems like the shape of the brushes are not smooth anymore, the raised terrain gets something like a triangular form. The same for every brush/strenght.
Also when I try to add the Terrain Tools package from package manager I get a warning with this message (the same with every Terrain Tools version).
Hidden/HDRP_TerrainVisualization shader is not supported on this GPU (none of subshaders/fallbacks are suitable)
