Better Seats

Better Seats is a Fabric performance mod for Minecraft 26.3-snapshot-3. Mojang calls the new seat entity a Cushion in code. Large builds can contain thousands of these entities, so their per-frame rendering and synchronized server checks become visible costs.

Optimizations

• Cushion model submissions are coalesced by vanilla RenderType. The mod retains the vanilla model, texture, pose, packed light, and overlay for every instance while replacing one short-lived submit object per cushion with a reusable batch.
• Within the batched path, the static cushion model does not reset its unchanged model-part pose for every instance.
• Server support and fluid checks keep vanilla's 101-tick period, but their first check is distributed by entity ID so mass-loaded cushions do not all run the expensive check on the same tick.
• An optional render-distance cap is available for very large builds. It is disabled by default because a cap is a visible quality tradeoff. Occupied, glowing, and custom-named cushions are always exempt.

Vanilla 26.3 already batches model draw calls by texture. Better Seats does not replace that renderer or claim extra draw-call savings; it targets the per-entity allocation and model-submit work that remains before each batch is uploaded.

Configuration

On first launch, the mod creates config/better-seats.properties:

batch-render-submissions=true
skip-static-model-reset=true
max-render-distance=0
stagger-support-checks=true

Set max-render-distance to 16 through 512 blocks to enable the visual distance tradeoff, or leave it at 0 for vanilla behavior. Restart the game or server after changing the file. skip-static-model-reset only affects the batched path; set it to false to retain vanilla pose setup while testing batch compatibility. The client batch and server staggering can be disabled independently.
