I didn't use the altered progs.dat and it still worked.

only effects 1 and 8 were really interesting.
I saw in the readme you can change the muzzle_bright in other options.
Qspecks can tell you which number to use. 

I have a sky emitting light throughout a level, but in one specific area, I'd rather it didn't, anyone know of a trick to achieve this? (And no removing the sky light and using lots of point entities instead is not an option). 

I think it is possible by adding a polygon within the sky brush, at least if the sky brush is thick enough to insert something inside it. I'm not sure but I think it is the way Quake shadow logo is produced in some Quake Level... 

Right, I remembered there was some trick like that, will try it out, thanks! =)

Anyone know any vis that supports dual cpu and dual core machines? 

I already asked aguiRe on that point some months ago.. aguirRe told me the very first vis.exe Id "release" was unix oriented and was supporting dual CPU usage. Unfortunately, he didn't think that any nowadays vis.exe is supporting dual CPU any more.
Maybe it will come back soon, as many brand new PCs have now dual CPU/core, that could support such a feature...
I think aguirRe would have better infos than me on that point ;P 

the quake logo shadow thing only works because the skylight is simulated using a point light entity above the shadow casting brush.

I think Bal is using the light emitting sky texture thing.

Is there a way to fudge a sky texture's name so that it behaves like a sky but the light compiler doesn't register it as one?

Hmm. what if you compiled the level with a dummy texture for your fake sky so that the light compiler didn't treat it as sky, then replaced the dummy texture afterwards in the bsp using TexMex? I have no idea if that would work correctly but it's probably worth a shot. 

Yeah good point, probably wouldn't work with the brush technique... Will try switching the textures after it's lit, thanks for the idea. 

I expect that the texture switch will work with just one problem - the surface won't be marked as CONTENT_SKY. This means that rockets that hit the surface will explode rather than being removed, and other similar effects. I'd imagine that the texture will still render correctly though. You can see the same thing happens in DM3 as it was compiled with an out of date version of the bsp tools. 

I still haven't tried any of this as I'm still at work...
But considering my sky is just pitch black in that area, any trick to simulating a false sky? some pitch black liquid maybe? 

try the dummy light trick with a negative light instead, and darken the regular sky texture for that section of the sky. 

Is it really a problem that the sky isn't truely a skybrush though? All the ID maps have this behaviour and don't seem to suffer for it, so I'd still say use Kinn's suggestion unless it causes a problem. It was just meant to be a quick warning in case it is important. Black water brushes would do a pretty good job of simulating sky if it does matter, the thicker you can make it the more likely it will be that the sound isn't audible. 

only one sky will show

My suggestion. I didn't see Preach's answer that fallowed until now. 

Did I need special build-tools to compile a map for nehahra?
At the moment I use txqbsp, rvis and tyrlite for fitzquake compiling
and it worked fine.
But for the neh-engine, Iam not satisfied, because the test-map is to dark and the brush that should be transparent, is not transparent at all.
Did I need other built-tools and other additional command-line settings
for this engine?

No you don't need any specific tools for Nehahra maps, just place the right entities in your map (according to the devkit documentation), and it should all work fine once in Nehahra.
Map too dark is probably just cause the engine is configured differently. 

Thanks for your help. You are right
the engine was wrong configured. 

I wanted to take a look at the teaching old progs thread but can�t view all threads.

What�s the specific key setup to create an explosive info_notnull?

It may be easier to just post the link direct to the thread.

Cheers.

is it somehow possible to have partial transparent textures in q1 like in half-life? 

not in stock quake. it can be done in tomaz quake with tga textures and alpha channels, but i don't know about any other ports.
