[C4D] I need help! / Noise/White Spots produced by Corona Skylight Volume Effect

« on: 2023-02-23, 01:07:52 »

Hi,
Anyone facing white spots or splotches produced by the Corona Skylight Volume? The Corona Sun & Sky themselves are perfectly noise-free but I noticed that the Skylight Volume is producing some white dots on the surface of water (simple Corona physical material water preset) which I couldn't get rid of.

To be sure, I increased the roughness in the water material a bit so that I wouldn't have a 100% glossy water surface but it didn't help. I also disabled the "show in reflections" in the Corona Sun parameters but it also didn't help. Any ideas? Maybe Beanzvision can help me out with this issue as well. Thanks,

*Something I also needed to add is that the strong straight line between the water and the sky in the horizon is not visible in the Interactive Render but visible in the Final Render. Maybe you can help about this as well.

[C4D] I need help! / Corona Render & Xpresso?

« on: 2023-02-19, 23:48:54 »

Hi friends, can you confirm if Corona is functioning well with Xpresso from simple tasks like set driver/driven to more complicated structures? I cannot figure it out if they work together well or not, it seems so random sometimes working and sometimes not working.. Any advice?

[C4D] I need help! / Animation render result different than IR

« on: 2023-02-10, 05:12:21 »

Hello guys, again this problem of difference between IR result and FR in Animation! When I simply save the image from IR in PNG format it's satisfying and enough but the saved frames...
Does the new OCIO OT has any role in this issue? When I simply save the image from IR it looks correct but the animation outputs are extremely dark. What's the reason? If the OCIO OT is only a tone mapping feature, could it be the reason?

In one word what should I do if I wanna see the final render the same as the interactive render result? Even the extracted Lightmix channel of the EXR in After Effects is very saturated, high contrast and totally different, indeed disgusted..
Thanks,

[C4D] I need help! / Rebusfarm Shared Shader Error!

« on: 2021-04-11, 14:32:30 »

Hi friends at Corona team,
I wish it's not a thread bumping, but I still get pluginshader error in Rebusfarm, I tried to save a copy of the scene without shared shaders (in Corona material node) and also tried loading all bitmaps one by one but I still get this error, some of the errors disappeared but I still get them. Any clue?

[C4D] I need help! / Wrong render output!

« on: 2021-04-10, 12:35:14 »

Hi friends!

Anyone having any idea why the rendered output is different than the IR? I mean at least the Interactive Lightmix Pass, it's darkened without denoising! Other passes look the same and chaotic.

[C4D] I need help! / Cannot render my animation project using Corona C4d!

« on: 2021-04-06, 07:25:02 »

Hi friends,
Is there any any correct detailed workaround / tutorial for rendering Animation using Corona in Cinema 4D? I cannot find any resources and seems people do it by experiment. The UHD stuff is very confusing... how many frames? how many passes?

[C4D] I need help! / Issue: Interactive Render Constantly Refreshing!

« on: 2021-03-20, 01:57:52 »

Hi,

Does anyone know why interactive render refreshes by even changing any parameter inside the interactive window? I mean changing the tone mapping & LightMix parameters refreshes the render. It's really hard or sort of impossible to work this way. Is there any workaround for it?
Thanks,

[Max] I need help! / HDRI Fireflies is a huge drawback for Corona

« on: 2021-02-26, 22:27:07 »

Hi all, I am still having problem of excessive noise with Corona when using HDRI, this problem has not still been solved? It's really destroying all the beauty of renders, I cannot in fact use HDRI with Corona, has anyone any idea about this?

[C4D] Corona Goodies - User Contributions / Product Visualization Scene For Download

« on: 2020-12-01, 20:14:58 »

I wanted to share this Cinema 4D / Corona scene for people who may find it useful. The post production file is not included, also the HDRI should be downloaded from the main website, it's replaced by jpeg file in the scene.

[C4D] I need help! / Unstable IR / Overheating Issue + Node Materials Editor Crash

« on: 2020-07-23, 08:35:19 »

Is anyone experiencing overheating or CPU overwhelming in Cinema 4D while using Corona interactive rendering? Corona IR looks totally very unstable in my Cinema 4D. It mostly crashes, even while tweaking nodes in Corona Node Material Editor. I would be grateful if anyone can help. Thanks

[C4D] I need help! / Cinema 4D Not using 100% of each CPU core

« on: 2020-05-27, 14:29:28 »

Anyone experiencing this issue?
While using Corona IR in Cinema 4D, it uses only 30% of each core, resulting in a very slow render. Any thoughts?

Hardware / AMD 3rd gen vs 2nd gen for "Corona Interactive Rendering"

« on: 2020-05-06, 11:56:38 »

Hi guys,
I would like to make my new custom PC. Corona Interactive Rendering is my main priority as I wanna see the result and play with lights of heavy scenes in real-time, I have patience for final render-time but not for IPR. This way, which one is better to go? A mid-range 3rd gen 3950x/3960x or a 2nd gen 2990WX, etc...?
I especially ask Jurai as he's expert in this subject but all are welcome and appreciated, I wish I can get his help as well. Thanks in advance.

Hardware / Threadripper 2950x and/or 2990wx Workstation Build

« on: 2019-01-08, 02:04:32 »

After a lot of research, I've finally decided on assembling a Threadripper workstation. Honestly speaking I am doing it for the sake of Corona, as I'd like to see its attractive output in realtime.

So I would liked to know your final thoughts on full specs for a 2990wx and 2950x (2990wx, if the difference in performance is huge regarding this link):
https://www.tomshardware.com/reviews/amd-ryzen-threadripper-2950x-2990wx-cpu,5797-8.html

I will do OC on CPU (if it's good on AMD) and lots of GPU Rendering. So I need good case/cooling system as well, a good X399 for CPU OC & 4 GPU slots for rendering in future, also about GPU type: for example 2 1080ti or 4 980ti? (regarding vram as a necessity for FStorm as an example).
That would be great to hear from you. Thanks in advanced.
