fog not helping with optimisation Created 17 years ago2006-11-25 03:58:20 UTC by guy

So I stick in an env_evironmental_fog entity expecting it to raise the fps on my map, but it does a whole lot of jack! I thought fog was suppose to disable the rendering of objects beyond what you can see. But I turn on mat_wireframe and I can still see the entire level, nothing gets cut out and it's really effecting preformance. Am I doing something wrong?

Fog has a minor impact on the overall performance. You need proper optimisation in your map, Hint brushes, Areaportals, Func_details etc. And the Source engine is not good for very large outdoor maps, if that's what you're doing.

Unless you set a Z clip falloff, it's not gonig to improve the FPS-rate at all, and if you don't fully compile it won't have any effect either.

Yes, make sure you have z clip set to just behind your secondary fog distance.

ok thanks ill try that

Ok it seems to be working well except I want it to fade into black, so yeah i set the colours n everything but once i move really far away from an object this white sheet just covers it, it wouldnt mind it if it was an outdoors map but its suppose to be a long dark tunnel, its starts off fading completely black but as i get further away it flicks to white.

You need to set primary and secondary fog color to 0 0 0 (black) to make it fade to black.

yeah i did, and it does fade black. But then it suddenly turns white.

Try turning Fog Blending On/Off.
