The Code-Based Visual FX Suite for GZDoom (aka CodeFX) mod

This is a collection of basically every single trick in the book for adding enhanced visuals to Doom, without a single new graphic of any kind being used. This is composed entirely of GZDoom text lumps, such as decorate, gldefs, texture defs, and terrain defs.

The following new visual enhancements are included:
- Ambient/environmental fog/smoke throughout levels, creepy red fog around certain hell structures, and green gas left from when a barrel explodes
- Enhanced blood effects, featuring visible blood particles flying out of enemies when they are hurt and blood splats on the floor (meant to just provide a "vanilla plus" feel for people who don't want a mod as big and fancy as some of the big gore mods out there)
- Enhanced particle effects for explosive barrels, featuring smoke rising, nukage splashing, and green flames
- Enhanced particle effects for rocket explosions, featuring sparks, smoke, and burnt chunks of debris
- Enhanced particle effects for fireballs, featuring smoke, trailing flames, and explosive fiery impacts
- Enhanced particle effects for plasma blasts, featuring crackling electricity mixed with brightly color smoke
- Deep liquid (floor clipping) for water, nukage, blood, mud/slime, and lava
- Smoothed out animations for all flat liquid plus warp effects
- Smoothed out multi-layered animations for all liquid falls (including lava falls for megawads that use them)
- Randomized frame speeds for animated textures that feature fire or liquids dripping
- Smoothed animations for the glowing red rock wall textures
- Certain textures are now brightmapped by using themselves as their own brightmaps
- FIREBLU iS nOw PsYcHeDeLiC!
- Glow settings for many flats to simulate things like light fixtures casting light, liquids giving off light, and
certain environments just having their own coloration similar to Playstation Doom.

something over on the ZDoom forums,, or worked on an article in the ZDoom wiki. I studied and learned from countless others in the process of making this, and am extremely appreciative to all of them.
