Thank you. Well those are my first attempts at rendering with penguin, only about 4 hours practise. It looks like I will probably have to add bongo to my shopping list too now (I am just trialling it for now).
V-ray et al. were just way too confusing for me, not what I wanted.
If by temporal robustness/integrity you mean how the sketchiness flickers from frame to frame, I actually don’t mind a bit of that effect (in some of them)– I was hoping for it! Probably because I’ve seen it before. But yes having another look it’s excessive & distracting in the last three. I’m not sure how I would reduce that, probably do two or three separate animations and blend them together with after effects? I might try investigating that tomorrow!
I might try rendering one more time, with a different displacement/waviness, then superimpose or overlay them with transparency or blending mode or something.
My main aim with choosing a renderer was to not have to spend months/years learning yet another skill like photorealistic rendering (which I see that it most definitely is). I’ve already had to learn so many pieces of new software. It’s too much! If I ever need a photorealistic render, I would probably rather pay someone else to do it. I don’t enjoy it (probably because I never knew what I was doing).
However I do find rendering with penguin is more fun.
