How would I make a one-way-glass-type texture for an entity?

I'm trying to make an entity with a "cockpit" section that is only transparent when looking out from the inside, and will appear solid in any other cases. If anyone knows how to do this, either in Blockbench or Mcreator, it would be greatly appreciated!

(while i'm here, is there also a way to hide specific parts of the model to only the player currently riding it?)
