Hm, nice project here. I've been playing Heroes III for years so I'm interested in the outcome.

I was just stating a few different things that can cause a BSP problem !!

As for all the colours in the BSP view ... each one is just to let you see the different cuts. The actual colour used itself doesn't mean anything.

Try an experiment to see what I mean. The best way to learn this stuff is to try it out. Subtract a simple cube room and Add a small cube altar in the middle of it. Have it touch the floor, and rotate it so its a diamond in the top view.

Now Rebuild the map and take a look at it in the BSP view. You will see the BSP cut angle out from the altar all the way across the floor of the room. In a huge map with lots of these types of BSP cuts in it will cause problems.

Let's add a thin post into the room now. Have it touch the floor. Rebuild and BSP view it ... take a look at the thin BSP cuts that the post causes.

Now change the grid scale to 1 and select the altar and post. Move them 1 unit above the floor. (Of course having a PlayerStart in the room helps too - LoL). Rebuild the map and now see it in the BSP view. the floor of the room should be smooth ... no cuts like before.

Ctrl-P to run the map (without bots of course) and take a look at the altar and post. They do appear to be touching the floor - from the point of view of the player.

If you really want to see how doing this does help, take a look at the original Zahltag map and see the lots (and lots lots lots) of cuts in the BSP view. That's why that map had tons of BSP holes etc.

Now grab Dm-ZahltagOps. Open it in the editor and take a look at it. Most of the angled and thin BSP cuts have been removed. A map with MORE stuff than the original ends up having hardly any BSP problems at all, runs smoother (etc etc).

It takes alot of work, trial and error, etc. Sometimes when you move one thing a BSP error will show up on the other side of the map. You can follow the angle of the cut from the object that's causing it and trace it across the map to where the error is. There is the odd problem that is quite impossible to fix, because more wierd cuts happen elsewhere.

The bigger the map the more likely a problem will occur.

Another thing that tends to help is ... build your map using "subtracted" brushes. Keep the added ones simple (like a streetlight or other smaller object). And try and pre-plan the building of your map to use as few brushes as possible.

It does help decrease the number of errors that you'll have to fix up.

Like Buster said, the colours themselves don't actually mean anything... they're just there to emphasise the cuts in the BSP... lots of different colours at crazy angles usually means a high chance of holes/errors in the BSP, and could affect performance as well.

Completed the Capitol Brush UNR! You can see how it looks (if you add some things you can even play it ), and I will add the Brush itself as well as the playable UNR soon (there is not much to be added to the playable version, but some cool spots for snipes and powerups! Wonder why New World Computing made buildings just perfect for Unreal? )
Here's the brush UNR, openable with UED:

Feel encouraged to BSP-hunt there!

And here's the T3D:

EDIT:
AAARGH!!! I hate that message!!! Why can't I add those lights to the level?! The same error!!! What should I do now?!

Code:

General protection fault!

Hello, anyone reading this?

Managed to get it to work (mapped in Perspective mode and used Zoning, seems to have made effect). Here's the PT map, enjoy And rate!:

EDIT: Pictures added to the first post. Look them up!

I've completed the Marketplace of InfernoTown:
(No idea why the stalls look empty)

Nope. I've only completed 4 out of 16 buildings in the town (5 is in the works) and I still need the terrain...

Looking good...

3rd floor, the administration room:


Only one, small floor left to go, and then I'll start working on lights and sounds.
