I was only a personal statement, so I write “… I know”. I tested Thea some months before and don’t got it working for interiors. But your interior rendering looks great, nice photoreal. I hope we will see more of it. No problem for me if you find Thea is the best all rounder for you.
Also I used Octane for a few projects, because the nice realism at high reflections/refractions depth counts, but only the biased mode was working for my need, because than I got enough speed. The Octane 4 denoiser was a big step forward for interior renderings. But at Octane I missed simple lights for quick scene setups and so I leave it again. It was great for some specific projects for me.
Important for me is to have a render engine that allow to render so much as possible of the range of viz work. Enscape helps me to render interior fly throughs and dozen of views in a few minutes, that isn’t possible per V-Ray. Could be nice to hear where the advantages of Thea are.
