File Formats

3D

Source
The source format for tracks and cars 3D data is a AC3D geometry data file .ac or Blender scenes .blend. Do not edit *.acc files!

Game
3D data for the game can be stored as a AC3D file .ac or as a ACCC compiled file .acc.
Information about tracks or cars are stored in a XML file.

Target Tris/Polycount
For cars the target polycount at the moment is from 8k to 20k tris.
It's obviously better to not waste polys where they are not needed.

Texturing & 2D Artwork

Source
For artwork sources, please use Gimp layered images .xcf.bz2 and Inkscape .svg.gz files.

Game
Older game graphics use Silicon Graphics *.rgb image format. The prefered image format for the game is PNG. Large textures or preview images can be saved as a JPG with very high quality setings.

Important Pre- and Suffixes
n as a texture name suffix means no texture filtering for this texture, example: poutre_n.png
_arbor is a usefull suffix for transparent textures at tracks like trees or fences, example: tree1-forest_arbor.png
WI prefix mainly used for cars to render transparent images (like windows) at last, example: WI_glass-door.png

Audio

Supported audio format is .wav for Sounds and .ogg for music.
