Just like Create Aeronautics which this powers, Sable is an incredibly capable and impressive mod. The API is surprisingly easy to use for such a complex mods and the mixins cause less issues that you would expect for such an intrusive addition.

Unfortunately, Sable does get unstable if you attempt to enter the "shipyard", which is a position in every dimension millions of blocks out which actually stores your contraptions. This can be an issue on servers without a world border, however it is minor due to how far out this shipyard is situated. My only other complaint is how floaty the physics can feel for small contraptions.

The performance of this mod cannot be faulted given how tolerant it is of such a large number of physics objects and how complex these interactions can be at times.

Integrations between mods utilising Sable will never cease to interest me, and playing with one of the mods that utilise this physics engine is a must to try out what it can offer, I highly recommend it.
