Fast ImageFrame

Fast ImageFrames for Minecraft 1.21.4 (Fabric).

Client-side mod that makes item frames and map walls (map art, ImageFrame) much cheaper to render. Nothing is needed on the server, and everything looks like vanilla: map walls stay seamless and shader packs see the same geometry.

• Map atlas: the 128x128 map textures go into a few big pages, so a wall of maps is drawn in one call per page.
• Reduced frame model: only the visible faces of a frame are drawn.
• Baked map walls and item frames: frames that do not change are recorded once per chunk section and replayed as a whole (uploaded to video memory when no shader pack is used), with the backs of the frames kept apart.
• Animated images (GIFs of the ImageFrame plugin) stay baked while they play.
• Hidden frames culling: sections and frames hidden behind blocks are skipped.
• Light changes (torches, dynamic lights) are patched into the baked frames without rebuilding them.
• Works alone and with ImageFrame Client (official, unmodified): downloads, caches and draws its HD images.
• Works with Sodium, Iris (with and without shader packs), Entity Culling and ImmediatelyFast.
• Mod Menu opens a settings screen with a switch for everything and a tooltip on each setting.

Requires Fabric Loader and Fabric API.
