Re-Volt
Here are some of my first 3D models, they were made for a game called Re-Volt released in 1999.
There were no support for custom creations but with the help of programs made by fans and cheat-codes used by game developpers, it became possible to make custom cars and tracks.
There are several steps : modeling/textures, export, ingame tweaking (manual optimisation, gameplay and AI setup).
Sometimes files had to be edited in hexadecimal…
