1. self shadowing on guns seems to automatically be disabled the instant you pick them up. it can look kinda ugly, especially when combined with the other bugs found in the game.
2. I think there should be a self shadowing option for every type of object in the game. so a self shadowing option for characters, a self shadowing option for guns and items on the ground, and a self shadowing option for guns you are wielding.
3. there's something strange about the shadow bias on items on the ground. it makes for a terrible on and off darkening of polygons. is it possible to have this smooth in as opposed to pop up?
4. the light intensity seems to have been dramatically increased in some levels. these are comparison screen shots between old and beta. they are at the same gamma brightness and contrast levels. with color control disabled.

5. gloss is great and all, but there's such thing as too much of a good thing. tone it down a bit, it looks awful on the weapons. but that might very well be because of the overly bright lights as well.
6. also, the ambient for weapons seems to rise up as you go through brighter places. this might be a good way to otherwise simulate global illumination, but it brightens up too much. i don't think the ambient should ever raise over .2. raise the diffuse instead?
7. the diesel power campaign level needs more bots , it's too large a level for such few players.
8. the sound radius is too large. i realize this was intended as a feature, but tone this down a bit as well, it can get very confusing as to weather or not there is a threat nearby.
that's about it for now i suppose.
