RB Skin Forge

RB Skin Forge turns the assets you already have into Roblox-ready content. Upload an image and it produces a standard Roblox clothing template; upload an OBJ or ASCII FBX mesh and it cleans, scales, auto-rigs, validates and (if needed) decimates the model into a Roblox-ready mesh — all from one shared C# core.
