ArghRad 2.0

ArghRad has made some speed optimizations to Qrad3, and it adds many new features. Textures can be read directly from the pak files,
eliminating the need to extract them all. It also supports reading textures from a separate mod dir. It provides better control over how certain
types of surface patches are divided up. There are many options to simulate much more realistic directional sunlight. It adds many options to
control how lights fade out. Spotlights can be aimed using several new methods. Lights can even cast darkness! One of the most important
new features is the ability for entity brush models to cast surface light. This adds a lot more control over surface lights not previously possible,
such as setting different colors and styles like point-lights. Be sure and check out the <a href="http://www.planetquake.com/arghrad/">arghrad homepage</a> for some more information and some tutorials.
