Optimizing a large q3bsp with fog

[Nahuel]

Hello forum I am creating a huge and foggy q3bsp and I need to optimize it. I have questions about it. If i limit the visible distance... will be the map best optimized? can q3map2 optimize the map adding limits to the visible distances? I mean something like, "-farplane" switch from hmap2. What switch can i use for this? what suggestions can you give me about it? Thanks

Is it outdoors or indoors?

outdoors!!

That's what I feared! I don't think there's anything you can do.

1. Keep your texture size small (no more than 256x256)
2. Optimize your brushes (do not overlap them)
3. Use -meta in BSP stage

Look at these huge maps - http://mxl.cz/q3maps (Zastávka and School) - they work pretty well with my Darkplaces engine.

You could probably get away with vertex lighting the outside only, to save on lightmap space. You can do this by defining a specific q3map_ shader flag in your terrain shaders

Try adding "_farplanedist" "512" (or whatever value) to the worldspawn entity.

(This just based on looking at the q3map2 source code, I dunno if it actually works)

P.S. "fogclip" and "distancecull" are equivalent to "_farplanedist", but I guess "_farplanedist" is best since it starts with an underscore.

@Chip
What about your custom darkplaces?

@leilei
I am not using terrains, it´s for an experimental city , otherwise: can you give me details or tips to save lightmap space?

@andrewj _farplanedist works very nice, but i do not know if this really optimized the map

The q3bsp code is the same as the normal Darkplaces, so no change here.
