I'm thinking about buying Polybrush to do some smoothing and vertex painting on meshes that represent terrain.
They're not heightmapped Unity terrain, they're meshes that I've built using ProBuilder and other methods.
The terrain is split into separate meshes, so perhaps there are about 64 terrain meshes.
My question is - can you smooth and paint across multiple selected meshes? I believe one of the PolyBrush videos shows blending between a terrain and a wall but it's not clear if they are separate GameObjects or part of a single mesh.
