Well thanks. If you care to read, I can explain why I moved away from my beloved VRay; albeit temporarily.
VRay started giving me a headache in the last few releases (both Laub version and new Chaos group), a headache that I seem to be largely alone with. The more complex the scene, the longer it takes to quickly quit out of it during test renders… I’m talking 1-2 minutes to be restored back to the editor view to continue working. If I render high res light cache passes (4000 samples plus), I can quit out of this instantaneously, but if the process has moved to IR pass or final render, quitting the render is painfully slow.
Corona (as EricM says, is CPU based) does the same thing as VRay, but faster, without the headaches and with some nifty time saving features, such as throwing in 20 lights into a scene with a default value or 1 and then being able to fine tune their intensities and color on the fly. Not sure if VRay has this, or makes this process easy, but in Corona it’s two clicks and you’re there.
On the Octane vs Redshift front, I feel both are fun, but neither are truly production ready. Redshift has pulled ahead in terms of its usability and popularity for me and will likely get more attention in the coming years. I don’t love either for personal reasons, but have been forced to use Redshift in a production environment 3 times this year. Plus with Maxon’s acquisition, it seems the more logical choice moving forward. One to learn, even if I’m opposed to its professional use, due to perceived limitations.
