Make a VRM character from one full body image

What the creator does

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. The character generator page has the details and an API example.

Prepare your image

Use a neutral A pose with arms slightly away from the body, so the limbs read clearly.
Show the entire body from head to feet with a margin around it.
Place the character on a plain white background with even light.
Choose outfits with clear layers. Fitted clothing rigs easily, and long flowing parts can be refined in the editor.

Describe the character

Give the character a name and a short prompt. A useful prompt names the age range, build, hair and outfit, for example "stylized adult ranger, tall proportions, long hair, fitted layered outfit". Short and concrete beats long and vague.

Add proportion hints

You can set height to head, shoulder to hip and mass hints. These help the creator choose the closest reference rig. A stylized character with a large head suits a low height to head value, while a realistic adult suits a higher one.

Fit and refine in the VRM editor

After generation, continue in the VRM editor to fit the rig and tune hair and cloth physics. Check the shoulders and hips in motion first, then adjust the spring settings for hair so it follows movement naturally. The Character Studio is the place to continue with animation.

Tips for better rigs

Hands and feet read best when they are visible and separated from the body, so keep fingers relaxed and the stance open. Hair that sits close to the head is simpler to rig, and the spring physics in the editor can bring volume back to longer styles. If the first result feels off, adjust the proportion hints and run again. A small change to the shoulder to hip hint often picks a better reference rig.

Once the rig is fitted, try a few poses and an idle loop in Character Studio. Short tests expose stiff areas quickly, and you can tune them while the details are fresh.

Costs and access

A 1024 texture costs 1 credit, and 2048 or 4096 cost 2 credits. You sign in to run jobs, and the API needs a paid plan with an API key.
