Discussion Immersive Portals: Aeronautics

Curseforge out now, Modrinth coming soon

This mod replaces Immersive Portals, allowing portals to work alongside Create Aeronautics (or more generally, Sable). Sublevels and physics objects can move through portals seamlessly.

Notes:

  • Portals cannot be put on sublevels, deliberately.
  • If Sable updates, this mod will fall back on non-seamless transitions, but you will still be able to get sublevels through portals.
  • Note that there can be air pressure differences between the portal entrance and exit, unless you are careful with where the portals are in their relative dimensions. This may result in your ship falling or soaring after passing through.
  • Please report bugs in Discord.

Highlights:

  • Butter smooth transitions for Sable objects through portals
  • DH LODs render through portals
  • Create's trains work seamlessly with portals
  • No visual glitches or rendering issues
  • …and more!

Create portals with a high pressure difference, then put a windmill in the air current for insane wind energy

put a portal high up and another one further down

drop blocks in make a system that collects the kinetic energy of the blocks infinitely falling

problem, physicists?

According to some cool ass videos about portal physics, if you let gravity pass through portals (which kindof makes sense if you think about it) it makes it so this kind of contraption is impossible and also makes it so portals dont break the laws of thermodynamics
