[C4D] General Discussion / Light normal direction vs light emiting direction

« on: 2025-09-10, 12:46:46 »

Hi everyone,

I’m working on a project involving a special light panel that simulates the Sun. The panel is mounted horizontally on the ceiling and can emit almost parallel light in different directions. This creates the effect of the Sun moving across the sky, causing shadows from buildings and other objects to change accordingly. Is it possible to achieve this? A sketch is attached in the image.

Thanks for any advice

[C4D] Bug Reporting / Cinema 2025 does not provide options when saving an image

« on: 2025-09-10, 10:19:56 »

Hi everyone,

I unchecked "Use Cinema 4D color space" in the Corona preferences because I want to use the Corona color space to get the exact same colors I see in the VFB. I noticed that the saved image sometimes shows slightly different colors compared to the VFB when using Cinema color space.

However, when I do this, I no longer get the usual save options. For example, when saving as JPG, it doesn’t ask me what quality I want to save at. Also, the saved image seems to use the monitor’s default color space (BENQ) instead of the one I’ve set on the monitor, such as sRGB.

I think we should still have access to the save options even when using the Corona color space, and there should be a way to choose which color space the image is saved in.

Does anyone know how I can keep the save options available with "Use Cinema 4D color space" unchecked, and how to save the image in sRGB (or ideally full RGB)?

When I tested it in C4D 2025, it worked properly. The issue is with the C4D 2024.5.1

I am using Cinema 2025.2.1 and Corona 13 Release Candidate 2 on Windows 11. I had the same problem with previous Corona versions. It was also reported.

Hi,

I'm sorry I can't share this project, but I've discovered out how to fix the issue. The option COMPUTE AFTER RENDER in the BLOOM AND GLARE settings must be enabled. As soon as the bloom is computed during rendering, it is not preserved.

Hello guys,

When I try to simulate soft lighting by changing the COLOR MODE to SHADER and placing a GRADIENT, it works great; however, when I use a LAYER or MIXTURE SHADER and combine two gradients, the light appears absolutely black. Is it a bug or a current limitation?

Thanks

Hello there,
We've been trying to reproduce the issue but have had no luck so far.
Could you please try using the latest Daily Build and see if the issue persists?
Looking forward to hearing from you soon.
Kind regards.

I have the same issue. When I finish rendering with the BLOOM and GLARE effect applied and save the BEAUTY and BLOOM and GLARE passes, they are rarely or never saved. I need to resave it once or twice more till the effect is saved as well.

[C4D] General Discussion / Phoenix simulations

« on: 2025-06-20, 11:46:55 »

Hi Guys,

I know it was been discussed some time ago, but I'd want to bring it up again. Would it be possible to import Pheonix simulations into Cinema 4D and render them using Corona? I have the Premium license, however I really miss this feature in Cinema. I do not want to switch to MAX simply for the simulations.
Please, anyone who uses Cinema, support this request.

Kind regards

[C4D] Bug Reporting / Re: IPR rerenders with any tonemapping setting changed-stil in v12update2

« on: 2025-06-02, 14:02:39 »

Hi,

I'd simply like to emphasize how annoying this is. This issue with parsing the scene after any changes in tonemapping is just horrible especially when working on large projects. It was reported many months ago, yet there is no solution to this problem. Kindly look at this thoroughly and attempt to resolve the issue. Thank you.

Hi Guys,

I have installed the most recent Corona version and am having difficulties launching Cosmos. I receive the message: CONNECTION REFUSED. Any ideas on how to fix this?

Thanks

Hi guys,

I'm using Cinema 2025, and when I want to save a PNG or TIFF image, I can't choose whether to save it in 8 or 16 bit format, or if I want to keep the alpha channel. This choice is not displayed, as the image is saved directly as 8bit with alpha. Nonetheless, it works fine in Cinema 2024. Did anyone else have the same issue?

Kind regards

« on: 2025-05-26, 15:31:51 »

Hi Guys,
When using Corona Sky with the VOLUME EFFECT ON, a glitch occurs in which a white background appears from around 60% of the image height. It cannot be overridden with the SCENE ENVIRONEMT option.
Did anyone else have the same problem?
Thank you for any reply.

[C4D] General Discussion / Re: Multiplied alpha

« on: 2025-04-04, 10:37:49 »

I tried saving the image as 16-bit EXR (it's a shame we can't save CXR 16-bit from VFB) and opening it in Photoshop with the EXR IO plugin, but it always opens as 32-bit, so any conversion to 16 or 8-bit affects the colors. It is a little irritating. Is there a workaround?
