Lightning and Fog

[milasudril]

This is two bugs, but they might be related (shader stuff?)

• Fog affects HUD. Shouldn't the rendering of the hud ignore all fog settings. Now outsidefog results in hud always rendered at full brightness. I am using "bright" lightning mode.
• "Software" light mode implies full sector brightness when using outsidefog.

Everything works when ceiling is not FSKY_1

Fog settings in ZMAPINFO:

Code: Select all

skyfog=192
outsidefogdensity=24
fogdensity=8
outsidefog="8f 97 9f"

GZDoom version:

g1.8.2 (2013-06-23 23:33:40 +0200)

OS: Windows 6.1.7600 64bit
Graphics gard: NVIDIA GeForce GT630

For limitations with how the software renderer works these quirks had to be copied to the hardware renderer as well. Especially the 'software' rendering mode will faithfully preserve the way fog will affect lighting.
