I was fiddling around with Blender and Cycles and really liked their fluid implementation of Cycles rendering on the viewport.
In Cycles since the viewport is denoising in real-time for every sample, we can set a start sample so that the denoiser doesn't kick in before a set number of samples has already been calculated. That's the default behavior for Cycles. If we change that so the denoiser only kicks in at a later sample it behaves similarly to Corona or V-Ray.
The viewport rendering (similar to viewport IPR on V-ray and the "Interactive rendering in 3ds max viewport" as suggested on "The most wanted feature?" topic on the forum) alongside the GPU rendering with all the scalability that GPU rendering allows would greatly improve Corona experience, in my opinion.
I know GPU rendering and viewport interactive rendering may be in the distant future (or never happening at all) but can we, as of right now, start the AI denoiser on the first sample in order to simulate default Cycles viewport rendering behavior?
Note: In the video, I'm using a GTX 1070 Ti which is very far from the latest and greatest but it is still a smooth experience.
