This setup create us a procedural stone model from any shape. I have decided to create moduler models for game engine or can be use for animation project too. For game engine i reduce poly count for %10 percent and texture baking. After that it can be use in the unreal or unity with textures that created by Houdini. Just copy , paste and create your castle.
