Flashlight: Shader Light Engine

Added

• Real shadows — terrain is re-rendered from the flashlight's point of view, so shadows follow actual block shapes: a slab casts a slab, leaves cast a dappled mess. Reaches 64 blocks instead of 24.
• Settings screen (ModMenu → gear) — shadows, beam and night vision, applied live while you drag the slider.
• Night vision sharpening — the picture now visibly breaks into pixels, plus scanlines, bloom around hot spots, and grain that thickens as the battery dies.

Changed

• New beam shape — a bright hotspot inside a wide, faint corona, instead of a flat disc. Zooming narrows the spot and steals light from the corona, the way a real zoom head does.
• Smooth distance falloff — inverse-square along the whole beam, instead of holding up and then cutting off near the end.
• Up to 128 lights at once, and the 4-per-chunk cap is gone.
• Voxel shadows rebuilt (the Sodium path) — half-block precision instead of whole blocks, reach 24 → 32.

Fixed

• The beam jumped to the centre of the screen when looking straight down.

Note

Shadow maps need vanilla rendering. With Sodium installed the beam uses the voxel occluder instead — coarser and shorter-ranged, but still real occlusion.
