New Features

• Alpha tint and chunk fade are now applied to translucent geometry.
• The fragment shader for translucent lit geometry has been completely rewritten, and now implements ray traced hand light. Per-pixel light list-based block light is also available with graphics drivers that support subgroup operations and subgroupBroadcast with a non-constant index (most common drivers except AMD's for Windows).
  • The vertex shader implementation of light list-based block light has been removed.
• The option to apply a directional multiplier to ambient occlusion has now been added and is enabled by default (works towards #8).
• A sun path rotation of zero is now allowed (works towards #12).
• The sizes of celestial bodies can now be configured (works towards #12).
• End flashes now affect lighting in the end.
• Shadow distortion is now configurable and tuned better in the different profiles.

Improvements

• Opaque and translucent lit geometry now share the same rewritten vertex shader and vertex data format for much reduced code duplication.
• Light list colors are now manually packed using atomics when 16-bit integers are disabled, halving memory usage.
• A slightly faster version of the GGX specular D term is now used when 16-bit floats are disabled.
• Lighting-related functions are now shared between shaders for forward and deferred rendering, reducing code duplication.
• Emissiveness is now handled slightly better. LabPBR support is still not implemented but planned for a future release.
• The shadow bias has been improved, reducing various artifacts such as light leaks.

Other Changes

• The maximum effect of the Ambient Occlusion option has been increased.
• The falloff of light list-based block light has been slightly modified.

Fixed Issues

• Extensions may be enabled after actual code.
• Translucent geometry is lit incorrectly when rendered before the deferred lighting pass (Closes #15, Closes #18, Closes #19).
  • This was caused by some changes in vanilla Minecraft breaking an Iris feature that RenderPearl relied on.
• Blending and render targets are sometimes configured incorrectly.
