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

Other

• 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

• Tweaked bloom to make it less blinding

• Fix some bugs not relating to DH

If you are updating from a version BEFORE v2.0, please reset your shader settings

This version is incompatible with configs made for previous versions. Please reset your shader settings after updating!!!

Color options

• All the options relating to colors have been moved to the new "Colors" tab
• In this tab, you can select predefined color schemes to easily change the way your game looks!
• There are only three available for now: Default, Vanilla and Choc v7
• I plan to add one color scheme per major update from now on
• Color sliders are now relative to the selected color scheme. This was a necessary change to make color schemes work within the limitations of the optifine pipeline.

Better Anti-Aliasing

• Added SMAA, an advanced anti-aliasing method that leaves the image sharper than the other methods that were present in Mellow
• It is used by default in the "Fabulous" preset, alongside "Denoise only" TAA
