Since I don't know the UDK version being used I played it safe and loaded a relativity early version of DM-Deck.
As expected it loads only the BSP since I'm pretty sure you guys would have removed the original content.
So, I quickly made a textured level in UDK 10-10.. all assets saved in the map file and cooked. Loaded it up however it then crashes.. :/
Thinking back to BSP I tired a new map using BSP only.. Loaded it up.. however this time it works.
Maybe I'm doing something wrong here.. I guess I'll have to wait for official documentation and the games SDK.
That's about as far as I've got.
