Global shadowmapping

There's still baked shadowing in a lot of the videos, I'm calling bluff on that. --Legend286 18:19, 13 April 2011 (UTC)

The videos aren't representative of the game. Look at actual screens and you'll see the shadow maps everywhere. --TomEdwards 18:23, 13 April 2011 (UTC)

The screenshots look like they're from SFM, and in the gel picture you can clearly see lightmap artifacts.--Legend286 18:27, 13 April 2011 (UTC)

Allow me to show you that they're merely projectedtextures/prebaked. Both are in source, except one is an official game, the other is a mod.--ZombieDawgs 22:51, 13 April 2011 (UTC)

ZombieDawgs; just an FYI, the right one doesn't use a single line of (shader)code related to proj. textures... --Biohazard 09:44, 14 April 2011 (UTC)

This is what I can say so far from a BSP file of the leaked Xbox 360 version:

• Static lightmaps are still widely used (light, light_spot, light_environment and even brushes with blocklight textures)
• Dynamic lighting is realized with multiple env_projectedtextures, like in Alien Swarm
