Hi Tom,
thanks a lot for your quick reply!
I know that the reduced denoise on bump channel has been done from the reason you described (preserving more details in renders).
Your colleague Bengamin already figured this out.
BUT in real daily workflow, the result of this good intention is horrible - leading to extremely noisy test renders.
And test renders cannot take 3-4 minutes. They need to be done in 30-40 seconds, without being so horribly noisy!
In Core 1.7 this was possible without any problem!
Even on fast machines like my 2018 iMac Pro, quick test renders look noisy now. And sorry, a 6000,- EUR machine does have some horse power.
Us users DON´T need microscopic details as the main goal. They anyway appear in a final render with many passes.
We need super quick test renderings - without being super noisy! Because on test renders, 90 % of the project time is spent.
This should sound logical to your programmers.
I stress it out once more: with this reduced denoising and also that weird displacement when materials are stacked,
working in Corona has suddenly become very difficult and nerve consuming.
Especially while finding the look for a scene, the strong noise in test renders destroys all your creativity!
Of course my assumption about "sabotaging" was just a joke - but your team should really take those two issues super seriously, as they literally destroy what makes Corona great: simplicity, fast & beautiful rendering and intuitive use.
I really hope your programmers make it work again, at least like in Core 1.7.
By the way, I started to teach Corona to students at a university and I personally very much promote Corona...
But such messed up basic functions are not the best advertising for your future clients.
Looking forward to your reply.
Cheers, Lucian
