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.

Sorry, but the if R20 is unsupported in that version, it never will be in the future. We plan on changing the displacement behavior soon actually. If you (or anyone else for that matter) have a strong opinion on how that should be done, don't hesitate to write me a PM

Hi Houska,

thanks a lot for your super quick reply!

My suggestion about changing the behaviour on displacement: it should function exactly like in Core 1.7 !
Actually like the "natural" behaviour of C4D- materials.

Left material is only the base material. Polyselect - assign material (with displacement). That´s it.
Repeat on as many poly-selects as you please.
No big rocket science... native C4D-behaviour.

The displacements on the stacked materials MUSN´T influence or even cancel eachother... like it is at the moment in the release version...

C4D displacement actually combines using Alpha channel, but it works in a strange way in that 0-99% alpha is different than 100% alpha.

But disregarding that, if we concentrate only on the 100% alpha behavior, the topmost (rightmost) material overrides the displacement even if the displacement channel is turned off! This makes creating decals, for example, impossible.

So what we would do (and it would mostly be compatible with C4D's solution) would be to linearly blend the displacements of all materials with displacement enabled on the stack. If all materials had 100% alpha (or disabled alpha channel) and enabled displacement channel, this behavior would be the same as in C4D. But at the same time, it would be more logical and flexible.

What do you think about this idea?

Hi Houska,

I didn´t refer to any Alpha behaviour of displacement.
Only that displacements - applied on polyselects - should not cancel or influence eachother just because of being stacked materials. Neither the first material on the left should influence them.
This would be the important basic behaviour - in my oppinion. It was like this in Core 1.7

How they behave with alphas... your suggestion sounds somehow logical to me.

I attached you a C4D scene here with a displacement / alpha test which I made long time ago on Core 1.7
Works like one would logically expect it.


P.S. I removed the HDR from the scene... too big to upload.

Thanks for the scene and for your opinion! I think what we already have in mind will be much better for you than the current state.

Well the current state ( Core 3 ) is not optimal.

If it became like in Core 1.7 - would be great.

If you will make it even better - as you say - then, hey, you and the corona team are more than awesome! ( we all know you are... :)  )

I´m very curious for the new function.

And... please don´t forget to change the reduced denoising on bumps.
See how nice & clean the scene looks form Core 1.7 - even on a 6 year old machine and 1:30 render time.

Of course it has not all micro-details... But if one needs them, one simply gives it a few more passes and reduces the denoise.

This change will be released in one of the next daily builds. That means a few days or a few weeks at most.

Hi Houska.

That´s truly great news... :)
Can´t wait to again enjoy the full power of Corona.

It is such an inspiring software, a real creativity booster.

When one does interior design with it, you can literally feel the room and its atmosphere - almost like if it was real.
The air is literally filled by light.

The creators of Corona are true geniuses. Excellence of my Czech brothers... :)

Greetings to all of your team!


P.S. link to the daily builds?

The safest place to find the link for daily builds is https://help.c4d.corona-renderer.com/support/solutions/articles/12000033462-corona-renderer-for-c4d-daily-builds (in case the google drive link changes at some point and invalidates any saved version of the google drive link)
