What is used mask blueprint node by procedural mesh?

Can you be more specific as to what you mean? I have trouble understanding what you need help with.

Hey there @Mirro1871! BoxMask3D is primarily a material node in that it doesn’t really serve a function if you’re trying to work with procedural meshes. It can pass out a mask that works in 3D space, so you can use it for purely visual holes and such.
