You can change vertex size in Blender by scrolling down in the Themes menu in Preferences. The default is 3 pixels, which feels very close to the tiny object origin in size. I doubled that value to 6, which is closer to Modo's default vertex size and also makes it easier to select vertices.
6 different diffuse textures with 6 of it's specs and 6 normals 18 textures total for the entire material? But there isn't an error in the material editor. Should that be ok? It's like a component can only have 3-4 textures painted per square anymore than that will crash.
