How the 3D pipeline works

The same steps we use to make characters for our own games.

01T-pose checkA quick look at your picture. If it is not a strict front T-pose with a closed, neutral mouth on a plain background, it is redrawn that way, keeping the same character. Arms held out keep the hands clean.
023D modelA textured, game-ready mesh made from the T-pose picture, with PBR materials and the lighting taken out. Characters and props get their own triangle budgets.
03RigA skeleton fitted to the character so it can move, with walk and run clips when you ask. You get FBX for game engines and GLB for the web.
