about area portals

[Viceman]

I've tried to improve performance in my map with these, but when i build my map it says this:

FindPortalSide: Couldn't find a good match for which brush to assign to a portal near (1192.0, 1024.0, -6.0)
Leaf 0 contents: CONTENTS_SOLID
Leaf 1 contents:
viscontents (node 0 contents ^ node 1 contents): CONTENTS_SOLID
This means that none of the brushes in leaf 0 or 1 that touches the portal has CONTENTS_SOLID
Check for a huge brush enclosing the coordinates above that has contents CONTENTS_SOLID
Candidate brush IDs:


whats wrong? area should be sealed entirely, i checked it. Oh. and is it good to use portals in hl2DM?

They work with HL2DM, but that error has only happened for me when the area isn't completely sealed...

hmm.. in my map there's four doors splitting one area to two areas. Could it be that? well maybe i just figure something else, but is there any negative sides when using portals?

Brush entities (like doors) don't seal vis, so you'll have to put more areaportals on the frames (unless the doors are static).
