Have you tried moving your player start position to somewhere in the map?
1. Position the free look camera inside your level
2. Go to object mode.
3. Double click the player start mode.
Did you add any industrial type lights to the level?
I forgot which one it is that causes this error.
Also, make sure that you don't have any objects outside of the level.
yeah it might be that. i remember when i started making maps there was a chair that u put in and it would not apear in the map, then u would go to play that map and it would crash saying could not create chair01 or some thing . but it was that dam chair that killed it for me.
Sorry for not replying. but yes it did work, and I do hope to get my level submitted soon but I'm going to wait until Hapa_Hanu has another HNSO(High Noon Shoot Out) on his dinner server then I will test it and hopefully get it released by then. Oh, and you will be expecting two more new maps from me as well. (Sorry for bringing this old topic up, I just had to say something ).
