hi every one, i have been away for about a month, during the time, a new version has came out with the new charactor.
i go to run my level and i have one wall that is set to transpant, using the pink transaprnt colour, (cant remember the rgb values, i think they are the 255,255,0 or somthing) but anyway, with the new version the frame rate has taken a major fall, it was working wel before but now im geting stupid frame rates like a few a second, if that, its making the player unbelivably hard to control due to the low frame rate, my level works the same as before every where else its just that one spot.

i just want to add that i notice a strange slowdown when using the FadeOut command and look in the direction of the pawn executing it... look away, fast, look towards him, slow... after he's done fading out, it returns to normal. if i comment out the FadeOut command in my script, it runs at a high framerate again. maybe its a related issue?

i have just changed the wall so it's type is set to clip instead of window, and now my games works perfectly, i would of thought it wouldnt matter how you made ur wall see through as it does the same thing.
im thinking there is a bug with setting the wall to window and then using the transapernt texture, or does this function do more than alow you to have it see through

clip brushes are just used for collision detection and don't get rendered at any time
window brushes do get rendered and if a faces has transparency it even needs to get depth-sorted
