When we needed extra vertices for VCol, it was expensive and we used LODs
Now that we have clustered the geometry offline, and we can afford having more vertices, VCol is expensive (and doesn’t work with Nanite well) and we need to do blending with textures
Love the irony 🤣
UE5.5 there're 2 methods of texture painting on Meshes:
1. Vertex: standard (older). Been around for years. Doesn't work on Nanite, needs subdiv (more verts the better).
2. Texture: new method, requires Virtual Texture on. Works on Nanites & not, doesn’t require lot of verts.
