[C4D] General Discussion / Corona 4

« on: 2019-05-01, 00:48:11 »

Hey guys at Corona,

thanks for the improvement in Corona 4 Beta !

CPU AI denoiser works great.

The "standard" denoiser sill denoises much less on bump maps & round edges... not good at all. Waiting for improvement...
However, the AI denoiser is great!!! Will use it from now on as new standard! :)

Also the displacement on stacked materials & poly selects works super in Corona 4 Beta.
Not "weird" like in the actual release.


Btw... now quick test renders with low number of passes are possible again, thanks to the CPU AI denoiser...
Great for a fast workflow and many many many test renderings. :)))

Attached a quick render...  2200 pix,  50 seconds on an 8core Xeon W 3,2 GHZ (iMac Pro).



Congrats!
Looking forward to the release of Core 4.

[C4D] Bug Reporting / Beta A1 that works with R20 ?

« on: 2019-03-28, 16:57:58 »

Hi guys at Corona,

ist there a Beta ( pre B2 ) that works with C4D R20?

I mean specifically a Beta that does not have the "new denoising" that denoises less on rounded edges & bumps?
As well as with the old displacement behaviour on stacked materials ! ( Material on the most left is NOT dominant )

Actually, one that behaves like Beta Core 1.7  -   only that it should run on R20.
Core 1.7 runs only until R19...


Thanks for your replies.

[C4D] Bug Reporting / Rounded Edges & Bumps - VERY NOISY !!!

« on: 2019-03-03, 23:36:18 »

Rounded edges and bumps are getting much lesser denoising, causing huge render times.

Already discussed this bug with the support, who promised to fix this issue.

Total crap, when you need quick test renders. And in the daily workflow, this is the most important part, where most time is consumed.

Since no improvement has happened menawhile, I will re-post this again, including screenshots from rounded edges & bumps, properly denoised in Release core 1.7.
And badly denoised in actual core 3 / official release.

Makes the daily project work very annoying, destroying the creative process by super noisy test renders, especially in interior scenes.

Please fix this ! ! ! ! ! ! ! !

As well as the weird displacement, when materials are stacked !!!!
Also worked great in core 1.7.
Now it behaves as if someone programmed it who never really used Corona for real project work !

Corona quality management should very carefully watch what the programmers are "improving"...

To me it looks almost like sabotaging the software ! Too big rival for V-Ray ?

With a broken displacement on stacked materials and broken denoising in bumps and rounded edges, Corona ist literally mutilated!

[C4D] Bug Reporting / Beta 2 C4D - Strong Noise in rounded Edges !

« on: 2019-01-09, 00:08:24 »

Since switching to Beta 2 - C4D, strong noise / artifacts appear on all rounded edges !
This happens on native C4D-geometry, as well as on imported ones - no difference.

It only gets reduced by much longer render times... not good!

In the previous Beta version (21-12-2017) the rounded edges worked perfectly !
But the older Betas dont work on C4D R20 !???!

Can it be a bug in Beta2 ?

Makes it impossible to work like that. I hope the official release version does not has such bugs.


Thankful for any suggestion how to fix it.
