RenderPearl

Requires Iris 1.8+

New Features

• Implicit normals and normal map support 🎉

  • Implicit normals currently cause compile failures on some AMD GPUs! Please enable RP Normal Maps if the shaders fail to load

  Using Meteor

  Using purely auto-generated normals and smoothness

Improvements

• Further major improvements to index-based lighting

  • Lights are now de-duplicated based on position, concurrently with shadows, volumetric light and sky rendering
  • Lighting Level Of Detail is now based on range, significantly improving performance with almost no visible effect on quality
    • Added LOD Falloff and Lava LOD Bias options
  • The light index is no longer recreated every frame
    • The rate at which this happens is now controlled by the new Index Rate option
  • Tiles/work groups now only allocate memory for part of the global index, which works well because of highly effective culling
    • The ratio between global and local index size is controlled by the new LDS Ratio option

  

• The shader pack options screen has been completely redesigned

  

• Dynamic Color Grading has been rewritten entirely

  • The implementation is now multi-threaded and uses significantly more samples to gather accurate color data from the screen

• Implicit smoothness calculations are now relative to average surface brightness

  • This should make smoothness more consistent between materials

• The FXAA implementation has been improved

  • Fixed blending in the wrong color space

• More uniforms are now combined

• Precision of color and data buffers has been increased by using better packing

Fixed Issues

• Block light is incorrect on translucent geometry
• Indexed light sources sometimes flicker (reported by Farmer_Markus)
• Lava & water fog color is incorrect
• Shadow mapping is enabled in the nether
• Opaque hand and handheld items render at the wrong depth
• Volumetric Light is inaccurate and causes light leaks
