A full compile goes through three stages:
- bsp
- vis
- light
The bsp stage initially creates .bsp file with structural information. The vis and light stages take the existing .bsp file and modify it with portal and light information, making it into the final file to load in the game.
If you have not successfully run the bsp stage, then the vis and light stages will always be unable to complete.
You need to look at the output of the bsp stage, and find out why it is not working.
