Reshady

Added and changed

• Added coloured godrays through tinted glass, with controls for shaft thickness and colour saturation.

• Reworked volumetric fog with a froxel volume and tuned its contribution down: about 50% less at night and 15% less during the day.

• Added block-light contribution to cloud lighting and cloud visibility to PTGI bounce lighting.

• Added a full-resolution cloud layer over translucent surfaces and a full-resolution pass for cloud reflections in water.

• Built and trained the first learned history-weighting network, then developed a larger second network warm-started from the first. Results were about 15-17% better quality than temporal upscaling, at about the same framerate. EXPERIMENTAL, Expect bugs and issues!

• Added a learned-upscaling debug view and moved its controls to the Upscaling settings.

• Expanded upscaler training scenes with harder detail and motion, including foliage, glass, and thin geometry.

• Added special upscaler handling for flowers and other foliage, signs, fences, and iron bars.

• Changed water refraction to use the existing 75%-resolution path and added special upscaling treatment for water.

• Increased water-wave strength by 15% and extended reflection history for distant water.

• Added underwater visibility cutoffs and depth-based fading for refractions and shadows.

• Filled the reflection gap between screen-space and voxel reflections with screen-space reflections.

Bug fixes

• Moved cloud rendering to full resolution over translucent surfaces to address cloud edges and dark outlines.

• Adjusted temporal handling for moving entities to reduce ghosting.

• Added an early check before the costly glass search. This affects the glass search, not water refraction.

• Fixed a severe frame-rate regression in learned upscaling by changing how the shader evaluates the network.

• Reduced repeated screen-to-world calculations, skipped empty voxel regions more cheaply, and reduced work in the shadow geometry pass.
