Block Physics Overhaul
Block Physics Overhaul changes how blocks that float in air behave, so they can be built into arcs, pillars and girders.
What it does
The mod makes block physics more realistic. Blocks that would otherwise float in the air are no longer left unsupported, and players can instead build support structures such as arcs, pillars and girders. Installation needs SKDS Core on Forge. Both sides must run the mod: the client and the server each need it, and files target 1.16.5 only. The mod is released under All rights reserved and is not open source, although its source code and issue tracker are public.
Key features
Realistic block physics
Blocks react to support in a more realistic way, so unsupported blocks no longer hang in midair.
Support structures
Arcs, pillars and girders can be built so that blocks stay in place, using the new physics rules.

How it compares
Realistic Block Physics is another Forge option for realistic block behavior, with files for 1.12.2 – 1.20.4, both sides required and All rights reserved. Simple Block Physics takes a different route: it is licensed under the MIT License and runs on Forge and NeoForge for 1.20.1 – 1.21.1.
