im new to this and was watching the standalone installer tutorial and followed everything he said, but when i hit part 3 at the very end he was building the mod for ugx_mod and saw how much he had under that and when i went to go build it i only have mod.csv under there, he said i need to compile the map but i dont understand what he means to do because ugx_mods isn't under the compile section on radiant where else would i go to compile it?

When building the UGX-MOD you are only building the fastfile. The things that will be included will be inside the mod.csv which are going to be compiled into the fastfile. Just do what he does in the tutorial but ignore his IWD list for the UGX-MOD itself.
