I made some maps in UDMF with SLADE3, when I made the MAPINFO i gave map01 and map02 diffrent skies, names and music. I play tested the first map and exited the level, after the transition screen it threw in into the console saying "No player 1 Start" But when I used Idclev to warp to map 2 it worked without a problem with the name the skies and the music. I then created some map using the Doom Map Format, and it worked. I'm not sure what is going on and how to fix this.
PS : I started using UDMF about a month ago when I'ver been creating one map wads.
If anybody comes with a solution, thank you in adcance!
