VRM characters

Generate a character and match it to a VRM rig

Describe a character, or upload a full-body image on a white background. SimplexGen builds the mesh with Pixal3D, chooses the closest reference rig from body-proportion descriptors, and hands the pair to the VRM editor for rig fitting and spring-physics refinement.

This tool runs on GPU capacity. You must be signed in, each run is metered in credits against your account, and the API needs a paid plan with an API key. Anonymous visitors cannot start a job.

How it works

  1. Name the character and describe an outfit in a neutral A-pose, or upload a full-body image.
  2. Optionally set height-to-head, shoulder-to-hip and mass hints so the closest reference rig is chosen well.
  3. Continue in the VRM editor to fit the rig and tune hair and cloth physics.

Questions

Does this output a finished VRM file?

The tool generates the mesh and selects the closest reference rig. Rig fitting and physics refinement continue in the VRM editor.

Which characters work best?

Humanoids in a neutral pose with separated limbs. Quadrupeds need their own rigs and are not covered here.
