Ray Tracing on Metal

• Hardware ray traced sun and moon shadows for terrain on Mac
• Named ray tiers a pack can read, and a ray_query pass type for a pack's own rays
• Rays carry a block's tint and light in the hit record
• Tracing runs only when something reads the result, with GPU timing on each phase

Camera

• Aperture jitter for true depth-of-field stills: parked, the projection looks through a different point of a real lens each frame while the focused subject stays pixel-fixed
• Focus comes from a 512-block look along the view, and reported jitter is only what was applied, which also fixes a swim under TAAU and frame generation

Voxel Light

• Entity occluders and exact partial block shapes
• Block models off the 1/16 grid read correctly
• Mesh edits run on their own worker instead of Sodium's meshing thread
• blocks.toml can turn a block off as a light source

Graph and Speed

• Waits only for the compute work that blocks the next pass
• Sampler choice, parsed gates and fixed name lists are worked out once, not every frame
• A compute pass can read this frame's images in draw order

Tools

• Deploy verifies the jar and reconciles the launcher index
• Frame profile dump on a key, with capture tools and GPU timing on the mesh trace
