Alright so i ran into a little problem in my tool/sapien programs. I was watching a tutorial on my computer and doing everything it told me to and i got to the part about:

tool lightmaps levels\beginner\beginner beginner 0 0.9

when i go into sapien my preview window is black but the pink "Halo(" still works. I was wondering if i need to enter another number in place of the "0 0.9" or i needed to play with options in sapien. Help?

P.S
I am sure there is probably another topic on this but i just didnt find it and sense i am not sure weather it id a tool or sapien problem i didn't look for a tutorial yet, if you have one to help me with this please link me to it, thank you.

No i did forget the sky, that could be my problem. Should i add the sky in guerilla and then redo the structure command or just open it back up in sapien?

Just redo the lightmaps command with tool.

Alright, thank you both.
