Changelog — Pure Xray

Added

• New visible blocks: raw iron, raw gold and raw copper blocks; budding amethyst and amethyst buds/clusters; spawner; trial spawner (all states); vault (all states); heavy core. Each one is built from the vanilla model of its own version range.
• 1.20.2–1.21.1: fullbright now also covers the cutout, cutout mipped, translucent and tripwire layers (previously only solid blocks).
• 26.3: grid models for potted_poplar_sapling and template_cube_bottom_top_indented.

Fixed

• Block items in the inventory, hotbar, hand, item frames and on the ground had no display transforms (no 3/4 view, wrong size). Every model now keeps its vanilla parent, display and gui_light, per version (including the on_shelf display added in 1.21.9).
• block/block no longer carries grid geometry; it now matches vanilla (display only).
• 1.20.2–1.21.1 fullbright shaders now keep the vertex colour (only the lightmap is forced to full brightness), so water and tinted blocks keep their colour in the newly covered layers.

Removed

• Unused lightmap.fsh files from the 1.20.2–1.21.1 overlays (that shader only exists from 1.21.2).
• 34 legacy models from the 26.3 overlay that 26.3 never loads (the base copies remain for older versions).

Optimized

• All JSON minified: 37.8 MB → 18.8 MB uncompressed, so the pack loads faster.
• pack.png losslessly compressed (9675 → 8283 bytes, identical pixels).

Verified

• Simulated the pack against vanilla 1.20.2, 1.20.4, 1.20.6, 1.21.1, 1.21.2, 1.21.4, 1.21.5, 1.21.6, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1, 26.2 and 26.3: every block hidden or visible as intended, every parent and texture found, display transforms identical to vanilla.
• All shaders compile with glslangValidator.
• Known difference: in 1.20.2 the spawner uses the newer model with inner faces (from 1.20.3+), which looks slightly better.
