Subdividing faces for textures and complex brushes

Ether:
1) Short of adding a brush plush with that wall, not gonna happen.

2) Ari's already said it /~unreal/ubb/html/smile.gif

3) Basically cuts are the number of polys that are made on a given surface. Switch the 3D View's Mode=>Zone/Portal (I like this compared to the other one) and select a surface. Ever poly (which are slightly different shaded shapes on a surface) on that surface is a cut. Intersecting picks up on these though.

Aphex:
The reason for the "odd" cuts is because at all times the Unreal engine does it's best to occlude unseen polys. These additional cuts are the result of that. That's why you often don't see combination inside/outside maps, because on the inside fewer outdoor polys are seen and the BSP will cut the outside polys (like through windows for instance) and it will do that to any surface. It then proceeds to do the same for the outdoor looking inside.

Strange but they're always clever ways to work around such things.

Q1: You can add a sheet on top of the face (>= 1 grid unit above) to put another texture on it.

Q2: <me listens interestedly /~unreal/ubb/html/wink.gif>

The best advantage I can see to making complex brushs into one brush is
1. It will have fewer faces as one brush cause the single builder brush only sticks to the outside of the brush in question. So it doesnt include in the new brush any of the faces hidden from view in the smaller brushes of the complex one.
2. Convience. Convience. Convience. Its much easier to make something once then make it into a single textured brush and then use it over and over again if its needed.

Thats the best reasons I can come up with off the top of my head for the second question. As for the first you can use sheets but its a lil easier on the editor(you) if you build like a 64x64x8 cube or whatever size you need just make the smallest size the part that will actually be in the surface. Then aubtract it from the actual surface you want it to appear in and it will segment the wall in the shape of the thing you put there and it will be solid unlike sheet decorations. You CAN make it easier on the engine by making the brushes semisolid so they dont cut into the BSP tree. Fewer cuts = faster display of areas. Hope this helps

You'll always have a BSP cut for a subtraction as far as I can see. You can have semisolid/non-solid additions that don't cause BSP cuts. But UnrealEd insists on putting loads of cuts in strange places (ie flat brushes with nothing touching/intersecting/subtracted from) on my map, causing it to slow down nicely /~unreal/ubb/html/frown.gif

I'll see what I can do. Give me a couple days to get it and run through it. Generally map reviewing isn't a high priority with me.

Hmm Wanderer, my map is at http://www.belldom.demon.co.uk/files/CTF-WarriorBeta.zip
It's indoor & outdoor and is quite slow due to loads of outside cuts /~unreal/ubb/html/frown.gif
Any chance you can take a look and work out one of these clever ideas? /~unreal/ubb/html/wink.gif

Sure thing - cheers!
Any ideas will be a help /~unreal/ubb/html/wink.gif

BTW Wanderer, my map is an almost exact mirror, but I noticed that being around the red base is 5-10 fps *faster* than the blue base!!!!
(I built the blue base, then duplicated it across to the red side).
WTF has happened here? Has the duplication reduced some complexity or something?

Not sure, but I'm gonna bend some of the typical zoning rules and rezone a little around here and see what happens.

Hmmm - I had a look last night - I see what you did, but I thought you shouldn't throw in huge portals, and they are *huge* portals!
What was the idea behind them? Partition off courtyard/wall-top complexity?
Seemed about the same speed on my system though /~unreal/ubb/html/frown.gif

I have managed to speed it up somewhat by removing the water from the skybox.

Thanks for looking at it!

Yeah, like I said, I was gonna bend some of the rules. Guess it didn't work (sometimes that's actually cured BSP holes). Well, nothing comes to mind that can be done really.
