Fabric Forge Neoforge Quilt 1.20 – 26.3-snapshot-7 Optimization

Optimized Block Entities (OBE)

OBE is a fully client side mod that significantly improves the rendering speed of block entities but not just that!

You won't lose animations, this mod keeps the animations of animated block entities likes chest and shulker boxes, it also supports EMF and ETF, which means it is compatible with FA: Objects!

You should also check out Better Block Entities, it was the first mod to optimize block entities on 1.21+ and did that very well. Both mods do not work in the same way, but he gave me some inspiration and 1 or 2 clever tricks.

How it works

This mod renders supported block entities just like any other block, this means they are meshed into the terrain and rendering terrain is much faster than rendering entities so it gives a HUGE performances boost. To keep animations, they are only rendered through the terrain when they are static, otherwise it goes through the vanilla renderer.

Features

Improved FPS : Huge performance boost that scales with the number of block entities visible.
Better lighting on block entities : they now support smooth lighting and ambient occlusion.
Better render distance : block entities can be seen from a lot further away
Config : Every block entity optimization can be toggled, same for the ambient occlusion.

Performances

FPS: 760 OBE / 520 BBE / 30 Sodium only

_{Performance tests ran on Minecraft 26.1.2 with OBE 1.1.27 and BBE 1.3.5 with Sodium 0.9.0 in FHD on a RTX 5060 laptop, an AMD Ryzen 7 260 w and 16Go of DDR5 RAM}

Modded block entities compatibility

While OBE by default does not optimize modded block entities, the following ones have been implemented:

Quark's chests Since OBE 1.1.3 and Quark 4.1-481
Lootr Since OBE 1.1.23
Mods using Blueprint (Woodworks and more) Since OBE 1.1.36
Mods using BCLIB (BetterEnd and BetterNether) Since OBE 1.1.40

Why

Mods like this already exists like:

BBE, but it requires Sodium to run, isn't available on Neoforge (at least not at the time of OBE development) and heavily modifies Minecraft's block entity rendering pipeling
EBE, but it is sadly not updated anymore and isn't available on Neoforge

Both are awesome, the developers did great work but I wanted to make one that:

Is updated and available on most modern Minecraft versions
Is less intrusive, which means better compatibility with other mods
Is available on Neoforge as well as Fabric
Includes a way to support modded block entities

List of all optimized block entities

Optimized block entities

Chests
Shulker boxes
Signs
Decorated pots (with no pattern)
Skulls (with no custom texture¹)
Beds
Copper golems
Bells
Banners (only the wooden post, not the flag as that would prevent the animation)
Beacons
Lecterns
Campfires
Shelves

_{¹: Some skulls with custom textures from Hypixel's Skyblock can also be optimized by using this resource pack}

Trouble shooting

Invisible or duplicate block entities:

Only vanilla, indigo and sodium (embeddium on forge 1.20.1) rendering pipelines are fully supported, issues may happen with other ones like Optifine, Embeddium, Optifabric etc... in that case it is recommended to disable the OBE optimizations causing the issues using OBE's config screen.

Crash on 1.20.1 Forge with Embeddium:

You need the Forgified Fabric API mod if you want to use OBE and Embeddium at the same time.

Modpacks

Feel free to include this mod in any of your modpacks, telling me would be nice but is not mandatory.
