Ren's Ugc Toolkit for Roblox
Do I need both add-ons?
No, each one works on its own. Install both if you want the Recolour Batcher to export an FBX for every colour, because it uses the Checker's exporter for that.
Does it upload my item to Roblox?
No. It exports an FBX that you import into Roblox Studio with the 3D Importer, then you upload it the normal way.
Which limits does the Checker use?
Roblox's published UGC specs as of October 2026: 4,000 triangles, 2048 px textures, one mesh, and the accessory size boxes for Normal, Slender and Classic body scales. Layered clothing also gets cage, armature and bone weight checks.
