Q3 BSP to Q1 BSP?

Post by DusterdooSmock »

Is there any way to convert Quake 3 BSPs to Quake 1 BSPs?
And the same for MD3s..
I'm interested in this because I'm trying to port a Quake 3 mod to Quake 1 for fun.

I'd first ask the mod author(s) if they would share their sources and permit you to use them. With sources it would be easier.

q3bsp to .map : http://en.wikibooks.org/wiki/Q3Map2#Dec ... nto_a_.map

Converting q3 mdl to q1 mdl works mostly okay in a lot of circumstances.

Trying to take q3bsp .map and trying to convert to q1bsp will be a royal pain involving scale issues, leaks, incompatible entity classes and lots of other fun.

Unless the q3 .map source is simple and uses few q3 bsp functionalities, converting it to q1 is a fine experience is learning more about Quake 1 mapping. Leaks, incompatible brush shapes, incompatible entities ... I learned quite a bit about the q3 map format by trying to compile a Nexuiz map source (GPL obviously) into a Q1 bsp.

Oh yeah ... q3 bsp can have areas with more sophistication and when compiled into q1bsp a scene can have 30 times as many polygons and cause rendering for the q1bsp to slow to a crawl (things like stairs) because q1 cuts up surfaces for the software renderer but q3 is built for hardware acceleration only.
The night is young. How else can I annoy the world before sunsrise? 8) Inquisitive minds want to know ! And if they don't -- well like that ever has stopped me before ..

Thanks for the help guys. I'd ask for the source(s), but knowing the person who made the mod, he probably didn't keep any sources as usual..

Noesis works great for converting MD3 to MDL, i use that for converting some Quake 3 and Wolfenstein weapons to MDL, and it worked great.

Don't forget about http://www.icculus.org/qshed/qwalk/ for converting MD3/MD2/MDL models.

I made a Quake 2 conversion of the Base1 level to Quake 1.

I did it with q3map2toolz and it converted the base1 file to a rudimentary Q1 map.
It took some time before Quark would open it after replacing all the texture and q3 defs into q1 defs.

Packed it up with q3/q1 texture and places it in the Quake 1 world as Orb's betrayel.

For a mod I think it is quiet a lot of work.
The level took me some months.

Here's a link to q3map2toolz :
