how is the info about kakashi's attaining kamui of the MS not relevant???
It said he was able to gain MS in obito's eye through training his chakra till it was powerful enough to invoke the MS we saw obito already awakened 16 years earlier through a telepathic link between him and his eye in kakashi...
This was in all liklihood because kamui of obito's MS is a senju/uchiha technique... which is why obito could use the technique and kakashi could not..
Obito has half a zetsu/hashirama senju body and half an uchiha body... thus he can produce the power of YIN and YANG elements for a more powerful doujutsu... which is why obito can use two different variations with his kamui which are more like two separate jutsu though...
While kakashi... at age 30 gained enough chakra as a hattake/uchiha to invoke the MS that had already been awaken in the SG by obito... but could not muster enough chakra as a nonsenju to use kamui properly thus his half ass use of his kamui... able to transfer anything into another dimension, but incapable of bringing it back out like obito can, plus another variation/jutsu...
