• Small optimizations

• Rework ambient fog & underwater fog. It should look much nicer and behave better with Voxy & DH

• Optimized depth of field effect & made it work with lod mods
• Fix seasons with voxy

• Fix compilation error with voxy mod on nvidia hardware
• New end portal effect

Dynamic Shadows

• This should bring mellow more in line with other shader visually
• While I optimized them as much as I could, they still cost a lot of performance. This is why they are off by default. This might change in the future though.
• You can enable them in the shader settings. I put them right on the front page!

Voxy support

• Voxy is a mod that renders far terrain using lods, with higher detail than Distant Horizons. Mellow now supports it.
• This feature is experimental. Expect some bugs.

Colorwheel support

• This mod gives higher performance with Create and shaders. Mellow now supports it.

PBR support

• Added support for labPBR 1.3 resource packs. Once again, this is off by default for performance reasons
• Normals, specular reflections, texture AO, emissiveness and SSS are supported

More cool effects

• Added chromatic aberration
• Added color balancing options
• Added a channel mixer option
• Added a world outlines option

Season coloring

• Added on option to change the color of foliage based on seasons
• Each season lasts 30 minecraft days, A new world starts with spring

Other

• Switched to glsl version 400. This allows me to write cleaner code, and use advanced functions for more performance (in the future)
• Added settings for border fog and underwater fog strength
• Fix z-fighting on banners and texture overlays
• Improve the aspect of terrain from lod mods with SSAO
• Improved aspect of handheld lighting
• Fix some other minor bugs

• Reworked ambient fog work like how it does in real life
• Godrays now affect ambient fog instead of doing their own thing
