I've scoured both HM and here trying to find a reliable source for reference or instruction. I haven't been able to find anything that tells me specifically how portals work.

My problem is that one side of the map is looking at the majority of the level while the other isn't. Now, I've looked at the HEK, but that technique does not do much. I've looked at this (http://www.modacity.net/forums/showthread.php?t=5064&highlight=portals) which I thought I could use, but I am not sure how portals are used to define what areas to render. I do not understand how portals determine what geometry is rendered and which is not.

Which is why I didn't bother posting until it was absolutely necessary.

It may be the direction of your normals. I think its north and east they should be facing.


Per HEK:
Make sure that the normals are consistent for all the faces, this will determine how the portal volumes are created. In the example, the faces running "East" to "West" have their normals pointing North, while the faces running "North" to "South" have their normals facing "East".

also remember your portals do not have to all be perfectly square.

You can also reduce poly count where it is not needed, here:

the optimize or multi-res tools in max are wonderful most of the time. I would suggest using one...then devote a little time to fixing some errors they cause.
