- 01
Copy the working structure
Keep the scene hierarchy, controls and feedback loop before changing the theme.
- 02
Make one idea your own
Swap the subject, camera, palette and signature interaction instead of rewriting everything.
- 03
Upgrade the 3D assets
Generate original characters, props and environments in Tripo once the prototype works.
Create detailed 3D assets
Give your next scene a character worth a closer look. Create detailed, textured 3D assets from an image or a few words.
