ok im new to map making, and ive had quite a few errors in my efforts that im not able to solve myself, and when i do, i post them here for help.
anyways, some issues ive had...
1)in sapien, when i run radiosity, i end up with purple mist that i cant find anything in except for my box used for frame. i made frame a distance away from the map. i might be able to solve this myself
2)in sapien, i try to spawn a downloaded tag, it says something anout how the tags couldnt be loaded correctly, and that i should contact my nearest bungie programmer
3)BIG error when i open a scenario tag, it says i tried to open a non-scenario tag, even though it is a scenario tag. this started when i tried to set scenario tags to automatically open sapien when i chose them. in the mean time, i use a_hobo
4)when i try to open some scenario tags, i end up with it running for awhile, then closing
if someone can help me, please do

1) Add a skybox to your scenario in Guerrilla, near the top. Also, run radiosity in tool until final release, then you can use sapien.
2) Look at the game window in sapien after the error message, and try to get the tags it lists as missing.
3) Do not open scenario tags this way. Open sapien, then choose the scenario file. Same goes for guerrilla.
4) Look at the debug.txt for whatever is causing the error. Could be missing or corrupted tags.
