RenderPearl

Only supports Iris 1.7.1-1.7.5

New Features

• Dynamic Color Grading:
  • Uses data from multiple frames to automatically adjust exposure, color balance and black point before/during tone mapping
  • Replaces Automatic Exposure
• Held dynamic light sources
• PBR Neutral and SBDT tonemap operator support
• Specular Map support (a bit more properly this time!)
• Small utility features (can be found in Misc):
  • Light Level Visualization
  • Simple compass overlay

Experimental

• Colored Block Light:
  • Colored light with glossy BRDF-based reflections, with brightness based on Vanilla lighting
  • Uses both SSBOs and Custom Images
  • Varies significantly in performance and quality
• SMAA - Enhanced Subpixel Morphological Antialiasing:
  • An alternative to the existing FXAA that preserves more sharpness and clarity
  • Currently experimental in RenderPearl due to some issues with it's implementation

Improvements

• Switched from Phong to BRDF lighting
• Improved shadow quality and performance using a fast gaussian blur approximation:
  • Can be toggled for solid and translucent shadows, or disabled to use the Linear and Off (Nearest) blur options
• Improved the skylight color calculation
• Used faster texture sampling functions where possible
• Switched to RCA Sharpening
• Made moon phase affect moonlight color
• Lava is now recognized as a fluid and has waves!
• Switched to a more accurate sRGB <-> Linear conversion
• Renamed Translucent Shadows to Subsurface Scattering, and improved its quality and performance:
  • There is now another list in block.properties containing blocks affected by SSS (which can only be of cutout type)

Removed Features

• Variable Penumbra Shadows (because it didn't work with the new shadow blur)
• Reinhard-Jodie Tonemap Curve option
• Emissive Flowers and Fungi options (as they were incompatible with the new SSS)
• Cloud lighting calculation (which didn't even work)

Other Changes

• Reverted default profile back to High
• Lowered default Volumetric Light amount
• Enabled RCA Sharpening by default
• Disabled shadow interval snapping

Fixed Issues

• Dropped items render incorrectly
• Enchantment glint animation is frozen (reported by drakray)
• Entities are treated as water in the shadow pass
• The BLOCK_EMISSION_ATTRIBUTE Iris feature is used but not marked as required
• Some post-processing effects run in the wrong order
