Ok, I can't seem to correctly portal this area of my map.



I put a caulk brush underneath the terrain, made sure that it matched up perfectly. I filled in the MG hole next to the gate, filled up the gate, and cut brushes to fit around the warehouse. It still tells me that the brushes have the same cell on both sides.

I ran the pointfile, and it looks like there's a leak at the top of the arch, but I can't find any leak, or any way to seal it up.

It's probably not necessary to portal this area, there isn't that much inside there (everything shown, plus 6 models), but since this is my first map, and my first honest attempt at portalling an area like this, I would like to figure out what I'm doing wrong.

Press 'CTRL + D' now make sure everything is sealed. This hides detailed brushes which are not solid and connot seal a portal.

From what I see...

1. The roof of that structure in the courtyard should be a detail brush if you're going to have a massive portal "lid" on the cell. As a matter of fact, you can either make that entire courtyard structure a detail brush, or make the walls of it structural brushes with a bunch of portal lids tiled on top, including the ceiling of the courtyard building.

2. The courtyard walls should be structural brushes.

3. You should have a portal in the courtyard doorways and any other doorways going into the cell. That means that the large structure in the distance (I'm assuming it's player-accessible) should have its wall as a structural brush and the doorways containing portals.

4. As for your leak in the arch, do the following. Make a square doorway in the courtyard wall. Place a portal over the opening. Then make a series of detail brushes to include two vertical boxes and a square cylinder that you bend around into an arch shape. The portal will cap off the cell, while the detail brushes make an arched doorway, simultaneously reducing the rendering while clipping the player appropriately.

This setup will optimize your rendering. If you do the tiled portal ceiling for the courtyard, stagger the portal tiles like it's shown in maskedavenger's tutorial (COD tuts, I believe).

The warehouse in the background is portalled, and I haven't had any problems with that area, so I know that there are at least no leaks there. I went through and made everything that wasn't a floor, ceiling, or wall a detail brush. Getting just t-junction errors now.

I pretty much completely rebuild the wall in that arch area, making everything that didn't give me a perfectly square opening a detail brush to simplify it. Still getting the brush sees into two cells error. The only thing I can possibly think of is that it has to do with how it's butting up against the doorways of the warehouse. You can see the two bigger doors in the screenshot, and I'm pretty sure the smaller door is at the same height. Is there a problem with the t-junction there?

The t-junction at those spots are basically

-+
-+ + + +
-+ - - -
-+
-+

with + being the portal side of the brush, and - being the portal no draw side.

med writes...The problem is T_Junctions are not allowed That is why you will have to split them.

Ok, then I'm an idiot and completely misunderstood the tut. split them, and it's at least compiling now, so hopefully it works. Thanks veef!

EDIT: Yup, it all works. Thanks man, I owe you.
