[C4D] Daily Builds / Re: IPR refresh often at change of tonemappng paramaters

« on: Today at 13:45:53 »

It doesn't make any sense to use the Release Candidate version or report issues in it. Please update to Corona 13 and let us know if the problem is still there: https://my.chaos.com/download/build?product=Corona&platform=Cinema+4D

What are your exact C4D and Corona versions? I tried looking for similar reports and there are similar ones on the forum, but I couldn't find any solution. Do you have any IES lights in your scene? If yes, can you try deleting them and see if the RAM issue remains?

We did have some similar reports already, but I did some housekeeping and it is now reported as (Report ID=CC4D-1059).

I agree with PT+PT for exteriors.

@394452216@qq.com - is it possible that the scene was originally made in some super old version of Corona?
Try this:
1. Open the development/experimental stuff rollout - here is how - https://support.chaos.com/hc/en-us/articles/4528523195537
2. Make sure that you have "texmap filtering" set to "all but opacity"
Once you do that, the blur parameter and render resolution should have no effect on the appearance of the opacity map (or minimal).

My advice would be to stick to defaults. You can get a really tiny bit of extra realism, but you risk adding lots of extra time to your rendering.
In Corona, using the cached GI doesn't come with some visible drawbacks like back in the old renderer times, you don't end up with things like missing contact shadows.

Which version of Corona are you using?

Can you open one of the problematic scenes on both machines and render it locally, without TR? Does it render ok?

What is your RAM usage when running TR? Perhaps it's some kind of memory leak?

[C4D] I need help! / Re: Tri-planar mapping scale has changed v13 using older files created in v12?

« on: 2025-07-07, 16:22:50 »

Sorry, it seems that I was wrong, and I must be missing something. I rendered simple materials with Triplanar, with Mapping Randomizer and without, using Corona Bitmap, and it rendered the same in V12 and V13. Could you share any scene, even very simple, where this is happening to you?

[Max] I need help! / Re: [solved] Environment override not working

« on: 2025-07-07, 15:41:26 »

Can you explain what exactly you would like to achieve?

If you mean environment overrides for glass, then you may need to use reflection or refraction overrides instead of the direct visibility override.

I can see that you have also started a support ticket, which is always the best choice for licensing-related issues.

[Max] Bug Reporting / Re: Aerial perspective produces the wrong result in some situations

« on: 2025-07-07, 08:49:31 »

When scattering is disabled, and only absorption and emission is used, it should render almost instantly.

Random idea: create a Corona Volume Mtl and enable Emission in it. Note that LOWER values make it glow stronger. Then assign it to a huge box (or other geometry) below the camera. You may also need to enable some absorption to make it look better. It's just a workaround, but perhaps you could use it?

« on: 2025-07-04, 15:14:54 »

I don't think this is anything we are aware of. I am not aware of any other forum reports or support tickets. If it was a global issue, I am sure we would be getting lots of user reports.
Personally, never happened to me either.
