'steempipe' and I have been working on the shader (well hes let me test it and throw suggestions at him
, heres what it looks like in a pseudo game environment...No its not a real game or anything, just a test hall for the shader.
PLEASE report which cards wont run it or sees only black walls so Steempipe can work on it. He said:
"IMPORTANT: might not run on geforce cards.."
(controls: AWSD to move, mouse to fire...)
