I'm using Radiant 1.2.13 but which BSP should I use to get everything?

To get everything? That's gonna take loooooooong...

Use this BSP command:
"bsp_Q3Map2: (final) BSP -meta, -vis, -light -fast -filter -super 2 -bounce 8"

You don't have to use the one ending in -bounce 8 - this enables radiosity which is a way of attempting to copy real life by bouncing light off of surfaces to light areas that usually would not receive light. Radiosity is up to you if you want/need it or not.

I usually use the ones labeled (test) since they don't take very long, and the end product is completely built, if not pretty or efficiently.

For a final project, use the final ones. But seriously, you shouldn't pump out a "final project" too soon. Make sure to test the map out plenty, and make "final" compiles when you think it's good enough to be released.

Make your own compile. Q3map2toolz. (http://planetquake.com/hro/webs/q3map2toolz.htm)

If you're lost with he BSP options in Radiant, don't use Q3Map2Toolz, it's great once you understand the options...otherwise it's a program with more confusion than the sexual orientation of Prince Charles!

OOO youre not supposed to talk about that :p
