I tried some more solves on this hypercuboids, face-shrinking after hypercube orientation helps a lot, MPU camera sometimes act weird. PLL skip is always well accepted.

How to do OLL on the purple cell(put all purple pieces on center cell)?

[@FlamingoLaRoccia]

I look for the 2c purple-other_color, and orient all of the except one, then I try to build 3d purple layer on the remaining 2c center and flip it outside.
If some pieces are still misoriented, flip another 2c and try to restart the process.
