After a quick watch of Rocket Lasso's video previewing these MaxonOne only assets, there was nothing there that would make me want to spend the extra money for MaxonOne. There are far more enticing elements to MaxonOne such as Red Shift, Red Giant and Z-Brush that a few extra capsules doing very specialized functions that you may only need once in your life (if ever).
The whole idea is foolishness (IMHO).
These should be free just like all the other asset browser assets --- all part of what keeps people renewing their annual subscription program in C4D.
Unfortunately, Maxon's confidence in their subscription program (evidence by the cancelation of perpetual licenses) has fueled their desire to create further monetization opportunities via these special capsules for MaxonOne only subscriptions.
This is foolishness as it will kill more customer goodwill for the C4D subscriber than it will create for the MaxonOne subscriber. MaxonOne subscribers don't need special C4D capsules to keep them in the program. They may not even be using C4D as their main toolsets could be a combination of Red Giant, Z-Brush, Forger, or Redshift (now that Redshift is being integrated into Z-Brush).
Now, what "may" happen is that the ENTIRE content library becomes reserved for MaxonOne license holders only. Just like it was ONLY for subscribers when perpetual licenses existed. But perpetual licenses are gone and the entire content library has been growing with each release. It is now a more meaningful asset than a few special capsules.
But, would it push people to spend another $480 USD a year on MaxonOne? Maybe, particularly if you relied on those assets and needed Redshift, Z-Brush and/or Red Giant.
But beware Maxon.....if you get that greedy than people can get Octane which gives you infinitely better assets and plugins for only $255 USD a year.
Don't you just love competition! It keeps foolishness in check.
