ive had some success porting source maps to v20 rather then poopy staticmaps, but its quite a janky process with results that require a forgetton of patching up before being functional and looking good:
some of gm_excess_construct:
i did end up finishing a map port into a complete downloadable map, and that is gm_flatgrass
this method of porting maps gives you results with just-about perfect collision with players and vehicles, and proper lighting with baked lights, but is also a pain in the ass to fix up for proper use on more complicated maps. and also the textures for big maps like gm_bigcity take up a
lot of space, which takes aages to download over a torque server
