While you made maps on these with creatings blocks instead of Meshes (well in UT you could do meshes...), it was alot easier and faster to work in.
You have to copy everything in GECK. Make a new room? Copy an old room, delete everything in it and rename it. Make new areas? Copy and search all the time. I followed the tutorials, and went to part 2 before I realised, that its really slow progressing in the Editor. Its a shame, cus I really wanted to do some nice work with it. And its probably only me with that opinion and everyone disagrees. Maybe im just frustrated over that the Grid screwed me over, when I duplicaed something, it didnt fit with each other even if I did the grip snap thingy.
Aint it possible just to easy put things inside it instead of this mass-copy-paste hell?
