[solved] Ugly spots when using sunlight

[spirit]

I'm having some trouble using sunlight in Quake 2:

Using sunlight creates ugly spots on the lightmap when using qrad3 v1.04:



With arghrad v1.0, there is no sunlight at all:

EDIT: Just updated to arghrad 2.01, no changes. Do you have to activate the sun on the command line because arghrad ignores the stuff in worldspwan or something? According to the readme, it should work from worldspawn.


Am I doing something wrong or are the tools buggy? Should I use other versions or something?

EDIT: Ok, I solved it myself. You need to define a light value (in the surface properties) for all your sky textures, then it works with arghrad 2.01. With qrad3 I get the spots, but I don't care. Using arghrad 2.01 instead.

there is a slightly newer version of arghrad that was in beta before argh dissapeared, which fixed some of the problems with the _sun features and had some extra command line options.

you can find it here:

depending on how the brushes are cut up in qbsp, it may still have a few weird graphical errors along the edge of certain tris when using too many light sources on the same surface.

I notice it works best if you use chopsky to ensure that your sky brush isnt being cut into a million more small tris than it needs to have.

spirit, it's entirely possible to compile Quake2 levels with q2wmap. Just use the -legacy switch.

Hm, that sounds like a great option. Thanks for reminding me!

Sure Don't forget to copy your .wal textures into ~/.quake2world/default in order for q2wmap to find them, too.
