Optimized Block Entities [OBE]

by maDU59_

Optimized Block Entities, shortened to OBE, is a client-side mod that speeds up how block entities are drawn on screen.

FabricForgeNeoForgeQuiltClient-side onlyGNU Lesser General Public License v3.0 or laterOpen source1.20 – 26.3

What it does

Supported block entities are meshed into the terrain when they are static, which lets the game draw them with the much faster terrain renderer. Animated ones such as chests and shulker boxes return to the vanilla renderer while they move, so their animations are kept.

The mod runs on the client alone and needs Fabric API on every loader. It is open source under the GNU Lesser General Public License v3.0 or later, and files are published for Fabric, Forge, NeoForge and Quilt across 19 release versions, 1.20 – 26.3. Snapshot builds are published as well.

Key features

  1. Faster block entity drawing

    Static block entities are rendered through the terrain pipeline, which reduces the work done for each one on screen.

  2. Animations preserved

    Animated block entities keep their movement by falling back to the standard renderer while they animate.

  3. Smooth lighting and ambient occlusion

    Block entities receive smooth lighting and ambient occlusion, and both can be turned off in the config.

  4. Modded block entity support

    Quark's chests and several other third-party block entity types have dedicated optimizations added in later releases.

  5. Per-option config

    Each block entity optimization can be toggled separately in the configuration.

Questions

Does Optimized Block Entities need Fabric API?

Yes. Fabric API is a required dependency, and it is needed on Fabric as well as on the other supported loaders.

Does the server need Optimized Block Entities?

No. Players add it to their own game, and a server needs no copy.

Which block entities are optimized by default?

Vanilla block entities are covered by default. Modded ones such as Quark's chests need their dedicated support, which arrived in later releases.
