And don’t forget:
As a previous OctaneBlender user I can tell:
-
You don’t have the large add-ons available for materials like E-Cycles has…
There is the LiveDB but it still crashes blender a lot, and some materials don’t work anymore
(they just turn any object transparent ;o) -
You need an internet connection to activate a license…
and hopefully it automatically deactivates after quitting (in case of crash it stays locked to the machine and can’t be used on another host) -
You need to create lights in Octane, as there are no predefined light sources…
-
Slow support…still on 2.80 beta…and as Mathieu mentioned…still no RTX though it was announced over a year ago…RTX is only available (and in beta state) in standalone Octane version.
Did last weekend (or better started ;o) a scene of our home and did two versions…E_Cycles and Octane…but soon I gave up on Octane and bought the RTX version…not only I can use all my plugins and materials…
And if you find a bug in the software…no one is faster than Mathieu to fix it 
just my 2 rappen (o;
