Create Smart Bounds
by LIUKRAST
With Create Smart Bounds installed, Create block entities on NeoForge get render bounds that fit their actual models instead of oversized or nonsensical areas.
What it does
Create Smart Bounds reduces the render bounds that NeoForge computes for Create block entities. Oversized bounds make the game draw machines that sit outside the player's view, so tightening them lowers rendering work. The mod also reworks how some block entity render bounds are cached. The author describes the effect as small, noticeable mainly in large contraptions and dense machine areas.
Render bounds adjustments apply to seven block entity families, including arms, conveyors, factory panels and frog ports. To inspect the values, the NeoForge debug command /neoforge debug blockentity renderbounds true shows them in the game.
Create Smart Bounds requires Create. It is a NeoForge mod for 1.21.1 and runs on the client only, so servers do not need it. The code is under the MIT License, which makes the mod open source.

What the author says
This mod aims to reduce enormous and nonsense render bounds for create block entities. You can check neoforge block entities render bounds with this command /neoforge debug_blockentity_renderbounds true It's a pretty small optimization, but in large contraptions and big machine areas, it can make the difference.
