14:59	scloink:	ok if a poly has rgb of 0,0,0 you cannot see it right
14:59	scloink:	does the engine still render it
14:59	scloink:	it does it ignore it
15:00	scloink:	it=or
15:02	ali:	uuhhh
15:02	ali:	things mixup
15:03	scloink:	huh
15:03	ali:	Do you refer to having black pixels in textures or to shadings?
15:03	scloink:	black
15:03	ali:	Then it still gets rendered
15:03	scloink:	I am asking that if I make the walls on my track clear will I get better framerates
15:04	ali:	What walls?
15:04	ali:	The blue ones?
15:04	scloink:	editor
15:04	scloink:	yes
15:04	ali:	You can't make them "clear"
15:04	ali:	They are colored only without textures.
15:05	scloink:	ok
15:05	ali:	Setting a color to black has nothing to do with invisibilty
15:05	ali:	It's just black
15:05	scloink:	but you can't see it
15:05	scloink:	in game
15:05	ali:	Turning them off (with the tedelete() option in glue3) will increase framerate
15:05	ali:	You can see it in game. It's black.
15:06	scloink:	not if you have rgb 0,0,0 then you can't see the texture it appears clear
15:07	ali:	But the blue walls aren't textured.
15:07	scloink:	ok
15:07	scloink:	I see
15:07	scloink:	another question to clear up my thinking
15:07	scloink:	:)
15:08	scloink:	if I have something textured with rgb 0,0,0 then is it rendered
15:08	scloink:	or is it ignored
15:08	scloink:	like a window
15:08	scloink:	instance
15:10	ali:	It's full rendered
15:11	scloink:	ok
