"sky" vis blocker


05-28-2003, 03:03 PM
How do you make a vis blocker that just looks like the sky? I have an arch in my map and I want to just have sky above it, not be able to see the rooftops beyond. There should be a way to do this, I just don't seem to be able to find it.

So far I've done a brush with all sky texture, and, at NC17's suggestion in another thread, a brush with all null texture. Neither worked, how do I do this?

Here's a pic I have used many times to help ppl with skybox. Don't care about that underground passage...

"you are not authorized to view this page"

its not really a skybox question. the thing is, a brush with sky texture on it should act as a solid wall that looks like the sky and not allow you to see anything behind it. for some reason it doesn't do this (anymore?).

so how do you make a brush that looks like the sky, and stops you from seing brushes behind it.

Sky brush isnt really sposed to stop everything behind it. It will take some of the brushs and will lower ur r_speeds. if u make ur SKy brush thicker it will take more brushs away. Just use gl_wireframe
2 and u will see what i mean.

not block vis, block view. how do you make it block your view?

OOO opsi. well the best way is just to make sure that ur skybrush is thick as possible.
and if the sky brush cnat be thick then rethink about redesigning that part of Archticture.

usually it depends on the angle...sometimes you can see brushes behind a skyblock and other times you can't...I haven't been able to determine what decides it.

Hm, sky and null blocks viewing of farther leafs but not closer ones. Engine draws full leaf so you may have see some faces behind such sky-ed brush.
The only solution I think could work here is to make horizontal hint brush placed at arch highest point, expanding to vertical walls. If area after the arch is longer you may have place another brush some meters after the arch and ending horizontal HINT there. So in the end you will make some box-volumes (new leafs. But you have to make it very carefully, don't know if the effect it is really worth it. Try some simplier vis-blocking.

In my conclusion, the sky or null brushes acted like a partial vis blocker, blocking vis, but not line of sight. As craftos explained, a sky or null brush still allows you to see "through" to the other parts of the level which are drawn because you can see a part of their vis leaf.

To fix this problem, you must not only insert the sky or null brush to block vis, but also block the player's line of sight into leafs beyond the sky brush in order to eliminate the drawing of these brushes, and prevent an incorrect appearance.
