UE3 - General Portal/Antiportal in UE3

[foxjasond]

I have been doing research about using portals and antiportals, and it seems straightforward. However, it seems like that these aren't in UE3?

Is this true, and if there isn't portal/antiportal, is there an equivalent?

Nop there arent any.

All normal meshes and all bsp now act as an anti portal and occlude things.

Thanks. If the portal/antiportal process is now automated, are there other ways to optimize a level done in UE3 (using materials, etc)?

 

[Hourences]

Yes there are a lot of ways to optimize a level. It is a complex and long story so hard to type out as just a reply on a forum, but things like the number of dynamic lights hitting the same objects, lightmap/vtx lighting, terrain size and tesselation, and so on all influence it.

I have a tutorial on how to model efficiently for UE3 on my website, and also an older article about mesh rendering in general. Those will help a little, but there is no definite guide online AFAIK.

Evilmrfrank has guide that covers optimizing really well:

Basicly what I try to do is to simply monitor amount of triangles and particles visible at any given moment.

Thanks for all your help, guys, these tutorials will really come in handy.
