OptiPainting Reloaded
OptiPainting Reloaded changes how Minecraft draws paintings, cutting the faces it renders for each painting block on Fabric.
What it does
Vanilla Minecraft renders every face of the blocks a painting is made of, including the inner faces that are never visible once the painting hangs on a wall. OptiPainting Reloaded skips those hidden faces, so a single block painting uses 8 vertices where vanilla uses 24, a 66% reduction. The author describes the gain as small per painting, and it matters mainly in worlds with many paintings. A 16x16 painting drops from 6144 vertices to a smaller count, and a 64x64 painting from 98304 to far fewer.
The mod is client-side only, so only the client needs it and servers run without it. It is published for Fabric alone, with files for 1.21.8, 1.21.10 and 1.21.11; the latest file, 1.1.0+1.21.10, targets 1.21.11 and dates from 2025-12-19. The code is licensed under the GNU Lesser General Public License v3.0 or later, and public links to the source and the issue tracker exist.
Key features
Hidden faces skipped
Faces against the wall and the inner faces of the painting blocks are not drawn, since the player can never see them.
Sides corrected
The two-pixel frame that sticks out from the wall is rendered correctly, so the painting edge looks the same as before.
Large paintings
Paintings up to 64x64 blocks also benefit, where the vertex savings add up across a large surface.
Fewer vertices per block
A block that vanilla draws with 24 vertices is drawn with 8, reducing the work the renderer does for each painting.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Art galleries
Builds with many paintings, such as galleries or museums, gain the most from skipping hidden faces.
Large murals
Very large paintings, including 64x64 ones, use far fewer vertices than they do in vanilla.
Who it’s for: Players on Fabric 1.21.8, 1.21.10 or 1.21.11 who keep many paintings in their worlds. Servers do not need the mod.

What the author says
This mod optimizes the rendering of paintings by not rendering the sides of the painting that are never visible. If you have a look at a painting, you'll notice that on the sides there is a 2px indented frame, so it sticks out from the wall. In vanilla, these faces are rendered for every single block that the…
