This is a procedural tool for generating old windows. First, base meshes are created manually with a base mesh generator. These are then processed with PDG to generate high-poly meshes used with Nanite in UE5. Instead of baked masks, I use vertex color masks for the triplanar materials in UE5. This allows me to use a single material instance (like the white window frames) on multiple meshes and keeps the process as procedural as possible. The triplanar materials are made with Jumpeters' material function for static meshes, which you can get here: https://jumpeter.gumroad.com/l/tri-penta-enna-planar
