.MAP format and brush grouping

[DieparBaby]

I'm writing a program that will generate a .MAP file. I'd like to group some brushes. I noticed that in Worldcraft 1.6a, the .MAP file does not have any grouping info but the .RMF appears to. Is it possible to have grouping info in a Quake 1.x .MAP file? If not, does anyone know the breakdown of the .RMF format?

Thanks,

I believe the best you can do is to group them into a func_wall entity.
Although thats not the same as a worldcraft grouping, will affect the bsp, and is a monkey, it will at least group them. You can 'fix' it by selecting them all and using the 'to world' option and then group them properly if you dont want lots of leaks.
There's a reason worldcraft doesn't save groupings in .map format.
