"Well, no weapon models for me"
Odd, you picked up the pickups, and then switched to a weapon with the number keys? I'll have to look into that one, I think it's possibly something to do with the curvevalue functions.
"The Storage level have a pretty messed up lightmapping"
In what way? It seems fine to me, although the level does take ages to load, and slows the framerate to about 30fps.
"And the Cashbah water was better in the old version."
You mean the shader is bad, or doesn't the shader work? In the old version it was just a dark plane I think (because the shader didn't export to the uploaded version).
"You reload actually really fast, with a reloading time of 0 seconds."
Yeah, we should wait for a completed weapon before finetuning the weapon system.
MikeS and Oddmind - Are you following the instructions on the Wiki exactly? It's odd that Skalex got it to work, but you two didn't. I'm pretty sure there isn't any missing media, or incorrect paths.
