LiteCraft Shader

LiteCraft Shaders v1.2 is for Minecraft Java with Iris, tuned for weak cards such as a GT 730 with 2 GB. Only the water surface changed in this version.

Water is no longer a flat coloured plane.

- Fine ripples come from a noise texture, in Worley or Perlin.
- Wave parallax shifts the ripple pattern with the view angle, so the surface has more depth.
- The surface moves with the wind.
- Colour, brightness, and transparency are set by the shader. A vanilla-texture mode is there if you want the old look mixed in.
- Water fog is always on while you are underwater. It can also tint the view looking down through the surface.
- Sun and moon glint is a GGX highlight, so the sparkle sits on the wave facing the light.
- The screen wobbles gently while the camera is underwater.
- Sky reflection uses a Fresnel curve. At a shallow angle the water mirrors the sky. Looking straight down shows the water colour. The reflection uses LiteCraft’s own sky. Clouds and light rays are not drawn in it.

Left out on purpose, so the pack stays on one post-process pass: refraction, screen-space reflections, water caustics, and coloured shadows through water.

The new page is Waving & Water, then Water Surface. Options are Sky Reflection, Sun Glint Strength, Wave Normals (None, Worley, or Perlin; normals cost 8 texture reads per water pixel), Wave Parallax (8 more reads, off by default, only Pretty turns it on), Bumpiness, Detail, Sharpness, Ripple Speed, Pixel Lock, Water Texture Mode, Water Alpha Mode, Water Fog, fog density, underwater distortion, and the colour controls.

The default water colour is a clear blue-green. Intensity is 0.70, tuned so water stays about as bright as in the previous version.

Potato turns off fine ripples, sky reflection, parallax, and underwater distortion. Fast and Balanced turn reflection and Worley ripples on, with no parallax. Pretty matches that and adds parallax.
