Game maps as OBJ meshes

This repository contains various OBJ files exported from Sauerbraten, Red Eclipse and Tesseract. These maps were exported using the /writeobj <destination> command after loading the map in the game.

Games

Maps were exported from the following games:

• Red Eclipse (commit ecfe18c51)
• Sauerbraten (SVN revision 5980)
• Tesseract (SVN revision 2343)

Caveats

• Maps are exported at a larger scale than you probably want. This may cause large maps not to appear at all once imported due to view frustum culling. To solve this, tell the engine to import the OBJ mesh at a lower scale if possible. Otherwise, you can scale the OBJ mesh by a factor of about 0.1. (This may reduce mesh precision, which is why scaling at import-time should be preferred.)
• Due to how maps are designed in Cube 2 engine games, their topology may be inefficient or otherwise unusual. This could lead to issues when generating collision meshes automatically.
• Maps don't contain mapmodels (detail models such as trees, barrels, …) and materials (such as water, lava and glass). You will have to readd those manually if desired.

License

See .txt files associated with each map for the license.

All maps in the redeclipse/ and tesseract/ folders are under free culture Creative Commons licenses (with commercial use and modification allowed). In those folders, CC BY-SA is the strictest license used, although some maps are under CC BY or CC0 instead.

Warning: Some maps in the sauerbraten/ folder use Creative Commons licenses that disallow commercial use. Still, modification is allowed as maps that use a no-derivatives license were excluded from this set.
