how come there is no include/exclude list for material override in latest corona for cinema?
I want to make my glass window still refract light.


[C4D] General Discussion / Caustics pass in corona4
« on: 2019-07-31, 12:51:19 »

I'm loving the quality and speed of caustics in v4.
However I have a quick question if somebody could direct me in the right direction.

I'm working on a scene with a pool. The only material on the scene that has the caustics turned on is the pool water. But I'm still getting a lot caustics action on the floor above the pool (see the caustics pass attached).
Is this normal or I have an error in my scene?


Hardware / Workstation configuration
« on: 2019-06-21, 18:15:18 »

I'm configuring a new workstation for myself and I would love to hear your opinions on the subject.
I'll be mostly running Cinema 4D + Corona.
I mostly work on archiz - houses or small residential projects with realistic 3D foliage.
My upper budget is 1800€ for the whole package (1gb ssd, 64GB rama,... LCD excluded of course)

I'm going to use it as a main computer, not a slave. So I'm expecting decent viewport speeds.
Since CPU represents the bottleneck for Cinema viewport performance my first thought was i9 9900K.

But now I started thinking about Threadripper 2920x.
Based on cinebench scores (,10.html) 2920x is 27% faster in multithreading compared to i9 9900K.
On the other hand i9 9900K is 22% faster in single thread rendering - how would that difference be reflected in the viewport speeds?

The other thing that confuses me are the Corona benchmark results - results of i9 9900K and 2920x are very similar. How come there is no noticeable difference in Corona speeds between the two? Should I trust Corona benchmark results or Cinebench results?

Any advice regarding graphic card much appreciated as well.
At the moment I have my eye on GeForce GTX 1660 Ti . Should I go with something cheaper since I'm working with CPU based Corona only?
Will it at all affect any viewport speed improvements when working with a lot of scattered geometry (grass,trees,...)


[C4D] General Discussion / Team render
« on: 2019-05-16, 13:03:42 »

I am trying out the Team render for the first time. I've managed to setup the machines and they seem to communicate between each other.
I've also installed the Corona Licensing server and I've entered the pass and username but somehow I still get an error on the slave computer saying "Several plugins used in this project are missing. Corona"

Can someone point me in the right direction?
thank you

[C4D] General Discussion / GGX in corona
« on: 2018-03-12, 19:50:25 »

I think there was once a topic regarding the GGX materials in Corona. (
Do we still need to merge multiple glossiness maps in one material, to achieve high realism in metal materials?
Or does Corona do it automatically and there is no use of using that workflow?

I think Corona does it, but I wanted to be completely sure.

[C4D] Resolved Bugs / Corona stops rendering, no crash
« on: 2018-03-12, 15:42:30 »
Hi there,

I've tried to render the final render over night. The render automatically stopped after 2-3hours. There was no limit set (time, neither passes).
Cinema didn't crash. It just stopped rendering.

Somebody else having same issues?


[C4D] Resolved Bugs / Very long "Preparing scene data"
« on: 2018-02-28, 18:54:45 »

I've recently started to notice very long "Preparing scene data" phase when I hit render.
Even if the scene is not huge. I can't figure out what's the deal.

I'm attaching model of the house I'm working on. I've completely cleaned the scene of all objects that might make the prep phase longer, very little improvement.
I get 20s of prep time on my six core machine, 64GB ram.

Can someone else try and report if he gets long times as well?
I'm using last version of corona.

Thanks for your help,

[Max] I need help! / Denoising in animation - interier
« on: 2018-02-12, 21:13:54 »

I'm about to render a 100s animation of interior spaces.
I'm getting some noise in certain parts of the images and I'm thinking of using denoising. But should I?
I don't have much experience with animation in Corona and I'm worried it might be some flickering?

Any advice would be apreciated!


[C4D] General Discussion / Z-depth & glass
« on: 2018-02-08, 15:16:31 »
Hey guys!

I'm doing some test renderings and preparations for final rendering of arch viz.
I'm planning to do DOF in post aftereffects by rendering a Z-depth pass.

So I'm having some trouble with setting up Z-depth so the black&white gradient would continue going inside the building and not stopping where the glass is.
I know I can re-render only the Z-depth map with the glass elements turned off, but I prefer doing it in one pass.

Is there a setting I'm missing?


[C4D] General Discussion / Deadline + Cinema + Corona
« on: 2018-01-31, 09:55:48 »
Hello everybody,

I'm close to finishing an animation project.
My friends have a render farm that uses Deadline ( to distribute frames across the render farm.

Does anybody have experience with working with it. Any issues or things I would need to be cereful about when rendering with Deadline?


Hello everybody,

I've just started out testing Corona's amazing LightMix feature.
However I have a question regarding saving finalized renders as .cxr in situations where I use "Stage object" to render multiple camera shots in a single project.
Under "Render settings/Save" there's not an option for .cxr. The only way to save it is directly from VFB, but in VFB I'm able to see only the last image rendered.
Is there a way I can open all imagse from my "Picture viewer" in the "VFB viewer"?

Thanks a lot,

Hi there,

I've been working on a scene and slowlly wraping things up for the final render.
I had to add a few more elements of geometry (simple cylinder + thorus) where things started to take a strange turn.
I get a crash everytime I make a region render, if I delete the newly added geometry everything works fine again.
I haven't even applied the materials on it, so it can't be that.
I've tried to make the objects editable, still crashing.
I've tried to copy the whole scene to a new scene.

I'm getting a bit frustrated cus I can't finish a project that needs to be finished.
Any ideas greatly appreciated!

Thank you,

[Max] I need help! / "Enable DOF" makes white render
« on: 2016-01-18, 18:10:38 »
Hi guys!

I've been using DOF without any problems. Untill now that is.
When I render with DOF disabled everything is fine (attached image).
But when I turn DOF ON I get a completely white render.

I'm attaching the whole scene so you can take a look.
What am I missing?
I bet it's something trivial and I'm just missing it.


Hey guys,

I'm trying to recreate the tutorial scene from this tutorial
I just can't get the same results (god rays are not visible at all, I have identical settings as in the video).
Has anybody had any experience regarding volume in Corona for C4D? Am I doing anything wrong or simply isn't functional yet?


Gallery / Kitchen, by Peter Zumthor
« on: 2015-10-16, 15:33:08 »

This is my first personal project in Corona for C4D. Well known Peter Zumthor's atelier in Switzerland.
There is some noise on the leather material on chairs and bench, I guess I'd have to wait a bit longer (or maybe the bump is to high?) Still need to figure that out.
Trees were made in Onyx.

Done in corona A3, a4 is too buggy atm.
Comments & critiques welcomed!


Software: Cinema4d, Corona a3, LightRoom + Photoshop, Onyx
