Thanks for putting up that Steempipe. I gave it a try ( even used the church you used for example) and it worked nice. but i ran into this problem. after running it once and tried to re run it I would get some very odd errors. rebooted my computer, would run fine again Once. then the same errors.

My guess is the fx file is setting soemthing in my video card then not releasing it after it runs? donno just guessing here...

error is typicaly this....
W1550
Error in effect:
floor1(26): error X3004: undeclaired identifier 'vecLight'

sometimes its wall3(26) error X3004: undeclaired identifier 'vecLight'
