The PNG files published beside this notice under their original REFI names are byte-identical copies

Modifications made by X-Builds:
- frame0: Animation strips (frames stacked vertically) are cut to their first frame; the atlas holds still tiles. Files: blast_furnace_front_on.png, default_furnace_front_active.png, default_lava_flowing_animated.png, default_lava_source_animated.png, default_water_flowing_animated.png, default_water_source_animated.png, mcl_copper_lantern.png, mcl_copper_lantern_exposed.png, mcl_copper_lantern_oxidized.png, mcl_copper_lantern_weathered.png, mcl_lanterns_lantern.png, mcl_lanterns_soul_lantern.png, mcl_nether_magma.png, mcl_ocean_kelp_plant.png, mcl_ocean_seagrass.png, mcl_portals_portal.png, mcl_sculk_sculk.png, smoker_front_on.png.
- mirror: Door halves are flipped horizontally. Their Mineclonia art is the mirror image of the orientation our door model expects (craft_to_clonia_textures' CloniaFlipsHorizontal table); the flip undoes that. The trapped double chest's front tile is also used flipped, for the half whose latch sits on the other edge. Files: mcl_cherry_blossom_door_bottom.png, mcl_cherry_blossom_door_top.png, mcl_chests_chest_trapped_front_big.png, mcl_crimson_crimson_door_bottom.png, mcl_crimson_crimson_door_top.png, mcl_crimson_warped_door_bottom.png, mcl_crimson_warped_door_top.png, mcl_doors_door_acacia_lower.png, mcl_doors_door_acacia_upper.png, mcl_doors_door_birch_lower.png, mcl_doors_door_birch_upper.png, mcl_doors_door_dark_oak_lower.png, mcl_doors_door_dark_oak_upper.png, mcl_doors_door_jungle_lower.png, mcl_doors_door_jungle_upper.png, mcl_doors_door_spruce_lower.png, mcl_doors_door_spruce_upper.png, mcl_doors_door_wood_lower.png, mcl_doors_door_wood_upper.png, mcl_mangrove_door_bottom.png, mcl_mangrove_door_top.png.
- colour: The grass block's top and side-overlay tiles are brightened ×1.3 (all three channels, so they stay greyscale for tinting): REFI's grass art is a low-contrast mid-grey, and with our tint the catalog ground read near-black. Picked by eye from our own renders. Files: mcl_core_grass_block_side_overlay.png, mcl_core_grass_block_top.png.
- atlas: Packed into the X-Builds block atlas: 16 px tiles in 32 px cells with 8 px edge-extruded gutters, colour bled into fully transparent texels, and three downsampled mip levels (premultiplied 2×2 averages; tiles with any fully transparent texel keep their alpha coverage at the 0.5 threshold).
- tints: Our tint colours for grass, leaves, water and redstone (build-engine textures/tints.ts) are sampled from REFI's own palettes: grass index 14 (its brightest entry, picked by eye); leaves index 0 (foliage), 2 (spruce) and 9 (birch); redstone power index 15; water is the mean of default_water.png. They are applied as vertex colour to REFI's greyscale tiles, never baked into pixels. Files: default_water.png, mcl_core_palette_grass.png, mcl_core_palette_leaves.png, redstone_palette_power.png.
