The Kappa Shader is the high-end shaderpack in my lineup and tries to deliver the most appealing results without resorting to complex techniques like voxelisation. It is generally considered a realistic shaderpack, although it takes its own shortcuts and liberties due to which it is by no means accurate in the sense of exactly recreating real life lighting configurations.

Key Features

Kappa Shader is known for its advanced and fairly unique Volumetric Clouds, which have been a cornerstone of its atmospherics and outdoor-visuals for a couple major versions now.

Version 3.0 introduced Screenspace Path Tracing (SSPT), which is also being used for light emission to allow for a wider variety of lighting colors within the screenspace limitations.

Important Settings

Atmosphere - adjusts visual properties of the sky and water

• Air - fog and mist settings
• Clouds - settings for both volumetric (cumulus type) clouds and cirrus clouds. Volumetric clouds are part of the signature look of Kappa shaders, though they do come with some performance load
• Dimensions - adjusts Nether and End atmosphere
• Sky - minor settings for sky light transmission and scattering
• Water - to adjust water volume, waves and color
• Sun angle
• Rainbows
• World Time Volumes

Lighting - adjusts properties of light and shadow

• Shadows - consider reducing shadowmap resolution to increase FPS at little visual cost
• Effects - settings for the Screen Space Ray Tracing (SSRT) [more investigation needed to determine settings with biggest impact on visuals and frame performance]
• Lights - adjust the strength and color of main light sources. Moonlight in Kappa is brighter than vanilla Minecraft, to make night-time in the outdoor over-world closer to the look of original Minecraft reduce Moonlight Multi to 0.5 or lower.
• Cave-Lightleak Workaround - can help to eliminate light leaking artefacts in caves
• Directional Lightmap - when enabled... [over to you RRe36]
• Minimum Ambient Light - effects exposure bias in dark spaces. Reducing the value increases darkness in shadows. Increasing the values bestows better night vision.
