Lighting renders randomly?

[Mikemc]

I am having a problem where the first part of the map renders fine. The second part is not directly connected but instead with a teleporter. There are areas where the light is either none, some, bad and perfect... all at the same time! These areas will render properly if the first half is not included in the build.

>Lighting bugs?
Now this is the kind of thing you don't wanna see after a long compile. The wall in the left picture actually is one brush. On the right a picture of q2dm3. It's hard to say what exactly causes these spots, but I know it's bugging me bigtime.




Fortunately you can get rid of them by doing one of the following:

> Check the texture angles of the bad brushface. Sometimes negative values like "0 -90.0" are the cause. Reset the angles to "0 90" and then manually shift the texture till it's properly aligned again.
> Select the brushface and slide the texture along its plane so it gets a new origin (slide it horizontally or vertically or even both ways).
> Delete the entire brush and create a fresh new cube that you turn into a new wall.
> If all this doesn't help make sure you are using QBSP3 Revision 1.09. This version of Qbsp may very well just fix these lighting bugs for you.

I cannot guarantee that it's always possible to get rid of those spots. But by using one of these methods there's a very big chance they will disappear!

what kind of lights are you using?

are you using arghrad's sun feature to produce any of that area lighting, or is it all entities?

[Mikemc]

Afaik it's all entities, but I'll go over the rooms again. I here there's an Arghrad 3.0 beta? And radiosity site doesn't have 2.1 for download, incase that's not the one I've got.

try the arghrad that's in this zip.
I'm pretty sure it's v. 3.0.



You could also take a page out of Maric's book, and just set the light flag on the sky brushes that make up the "lid" of your map to about 250-300 or so, and remove a bunch of the entity lighting..

This will make much more uniform lighting in the open areas that can see a lot of sky.

I've found that if you want a certain color of "sky" light, you can use a texture that makes the color/atmosphere you want on all the lit sky brushes, and when you apply the sky in-game, the lighting will be that texture's color, and the sky will look like whatever sky you set in the worldspawn settings..

In this way, you could use the standard q2 skies, and not have your level come out completely orange.

Nope, lighting still looks like shit. Could there simply be too much to render? I have a single processor and 768mb ram. If I can't get it working, I'll have to split the map into 2 separate levels. That seems to be the only way so far.
