Siwasky problem

(sani) #1

I’m having airstrafe at my gamma, you follow the tunnel and end up in some sort of cave.
You look up, and you see the begin of gamma.

I asked few mapping mates already, but since they doesn’t know any real answer, I decided to post it here.
I already tried to change the shader with modifying few lines but nothing worked.
A friend said that maybe some common shader could fix it, who knows?

This is one of the bugs I need to get fixed and now I’m almost desperatly in need of help.
Thanks.

what is the problem?

you see through the sky box?

Ah yes, sky shaders do that if you don’t use proper VIS-blocking.

If this is a singple-player map, you could try to use “hint” brushes and a door with an “areaportal” brush in it. However, you might then need to add other doors as well to close up the “areaportal”.

Another option is to make the passage to the cave into a z-shaped tunnel and use hinting.
The tunnel should be layed out like the image below:

Now, to make sure VIS knows that the two entrances should never draw at the same moment, add angled brushes in the passage which will tell VIS how to cut up the tunnel.
I added two for simplicity in each corner, but note that you could do with just 1 if you use this technique cleverly. See below:

These brushes should be completely covered in common/skip except for the side you can see as a blue line: that side should be covered in common/hint.

Tutorials concerning hinting can be found at Quake3World: Advanced Portal and Hinting Optimization Tutorial or at Tramdesign. If that doesn’t cover it, try Google. :wink:

I’m having hint brushes at different places of the map (other tunnels).
That tunnel is just short, straight tunnel, I wont make any curves to it.
It’s a trickjump map by the way.

In that case you cannot resolve this issue unless by using doors and areaportals (reducing the issue) or by throwing out the sky shader in the room you took the picture from.

“Problem solved”.
As professional as I am, I will give up with the sky. Flat, cave textured brush will be there.
Thanks for the help anyway.
