ok, first of all:

Windows XP Pro
BFG Geforce 7800 GT oc

the project is just using any post processing effects, any ones i use, i tried your bloom (to test with), and some of the other shaders in the shader forum and wiki.

with your bloom shader the only problem is that any models "except the ones with bright or materials on" will disappear, and i'm using the same code that was used in the demo
