First of all, I really really like Corona and the Corona team which has always been of support when I had a problem with the scene, a bug etc. so thanks for that
However, with the new 3000 series it's the first time when I EVER look into GPU rendering-> Vray GPU and Redshift.
Before spending 1500EUR on a GPU I thought to do some tests with the environment I typically use, large oceans, foam and boats.
The results were that on Vray GPU, a puny 1060 GTX(what I currently have) is slightly, just slightly slower than a 3950X Ryzen (Both Vray CPU and Corona) so price/perf imagine what a 3080 RTX (similar to 3950x) would do.
I have 2 huge problems with Corona, it renders big refraction planes unbelievably slow, as i posted previously it doubles the render times and the unending lights fireflies, as on yachts everything is reflective (ceilings, walls, floors, railings, glass, pools etc etc). If you add small led lights near these surfaces (ie steps lighting) I am screwed. I have to wait for about 3h-4h for the render to clean, on a scene where there is very little GI bouncing. GPU renders seem to perform much better in situations like these.
Now, Vray GPU is buggy and unstable as hell, Redshift isn't, it is much much more mature.
However Corona just feels more polished and the feeling that it just bloody gives the results you are expecting with little effort is gold.
My bottom line is........
Corona GPU please
I imagine there is a lot, a lot of work but reading on the Vray forums I will quote one guy working at some CGI studio ".Nevertheless, adding some cards, specially the new 30 serie, the speed increase may be enough to convince us to gradually abandon Corona and adopt the GPU way (with the lack of features and stability, I know)."
So... Please
Corona GPU I'm sure it will the best GPU renderer out there because you guys don't mess about when doing things.
Thanks!
