Short answer: you don’t usually “convert” a VRChat avatar straight into Roblox. The practical route is to rebuild or adapt the model in Blender, then import it into Roblox Studio and use Roblox’s avatar setup workflow to rig and prepare it.

Quick Scoop

A VRChat avatar is typically made for Unity/VRChat’s avatar pipeline, while Roblox avatars need to fit Roblox’s model, rig, and asset rules. That means the mesh often has to be cleaned up, resized, re-rigged, and sometimes simplified before Roblox will accept it properly.

In plain terms: think “porting and rebuilding,” not one-click conversion.

Basic workflow

  1. Export or obtain the avatar model you have rights to use.
  2. Open it in Blender and fix scale, materials, and geometry.
  3. Make sure the model matches Roblox avatar setup requirements.
  4. Import it into Roblox Studio and run the avatar auto-setup process.
  5. Test the result, then adjust rigging, textures, or accessories as needed.

Important limits

  • Not every VRChat avatar will work cleanly in Roblox. Complex meshes, custom shaders, and extra bones often need manual cleanup.
  • Roblox’s avatar tools are designed to accelerate conversion of custom models, but they still expect the model to meet specific requirements.
  • If your goal is just to recreate the look , using Roblox clothing, accessories, and body parts can be much faster than importing the full avatar.

Best option

If you want the avatar to actually function in Roblox, the best path is to recreate the design inside Roblox’s avatar system instead of trying to preserve every VRChat detail. That usually gives a cleaner result and fewer rigging problems.

TL;DR: use Blender + Roblox Studio + Roblox avatar setup; don’t expect a direct VRChat-to-Roblox conversion.
