Hi, just for fun I tried to launch maps from other games, here some preview… Nothing serious here, and I can't share more than screenshots since it's probably the only legal thing I can do.
All these maps runs unmodified (except the exception I will explain). The only thing I've done is to repack all the data for each game in a tex-package and creating map entries for each bsp with DEPS on this tex-package. So for example for q3dm7.bsp I created an empty map-q3dm7 that depends on tex-quake3 that contains q3dm7 (repacked pak0 and others officials) and sometime I have to rename badly named maps (for example obj_railhouse to obj-railhouse since “_” is the version separator). That's all!
Now the pictures:
1. UrbanTerror
2. Quake Live / Quake 3 Arena
3. Smokin’ Guns
4. Wolfenstein: Enemy Territory
5. Close Quarters Battle / True combat: Elite
Also, there is some time some missing textures, and many weird bugs like the #552 water bug (on tree leafs for example).
As you see some maps are overbrighten, with a 0.7 gamma it looks better:
6. Xonotic
Xonotic maps load but I did'nt manage to have textures working (only the skyboxes work out of the box):
7. Warsow
Warsow maps don't load at all (bad BSP version).
8. Exceptions
I made an exception for this map and only for this map, I modified the entities lump inside the bsp to add some spawn point. It's a community Urban Terror space-themed map named orbital, a good one to play Unvanquished.
The mapper wrote in the README he does not allow people to use his map in other projects than Urban Terror without permission, but perhaps I can ask for permission… There is a a bit work to do, add spawn points in entities, and replace some texture from Urban Terror (many textures in this map come from Urban Terror).
Now this other map is a subway-themed community map for UrbanTerror named metro (not the Tremulous metro map by KOsAD). In fact a guy ported it for Tremulous in the past, but that was a very bad port with many textures and brush issues: the guys said he has decompiled it with permission, but there is nothing to decompile here, only fix entities and use transparent textures to hide some Urban Terror themed objects… And this map run wells without q3ut4 paks (only 3 or 4 missings textures that are easy to replace). This map is very polished (more than common Urban Terror maps), if it was true the mapper authorized someone to port it and if he authorizes me, this can be fun.
