correct me if I am wrong but isn't genjutsu performed by extending your chakra into the brain of the victim and controlling their brain? If so then the user must constantly extend more chakra into the victims brain to maintain the genjutsu for longer periods(izanami being the only exception).
Now let us look at obito's fight against minato. Obito first took control of kurama via sharingan genjutsu to use its power against the village.
Now my question is how did obito maintain his control of kurama even after teleporting and also going into kamui world when he became intagible while fighting minato? The case is the same with Fu and Tourne. He was able to keep them under genjutsu for a long period of time even though he was in a completely different dimension from them? now don't say that he can send his chakra to the kamui dimension. This has been proven false because Kakashi did not receive naruto and minato's chakra when they powered up everyone because he was in the kamui dimension. This means that chakra can't be transfered between dimensions.
So how does Obito do it? thoughts?
