[Scatter] Resolved Bugs in 3ds Max / Re: Chaos Scatters heavily affecting viewport FPS

« on: Yesterday at 10:57:18 »

Yes, there were multiple performance-related fixes between Corona 9 and 11. I have the same suggestion as in the other thread:

Please update to Corona 11 Hotfix 2 - https://corona-renderer.com/download
Then test your case, and if you are still observing any issue, submit a new ticket at https://support.chaos.com/hc/en-us/requests/new

[Max] I need help! / Re: Corona render selected objects is terrible

« on: Yesterday at 10:56:00 »

Hi, yes, there were improvements to this in V10 and V11:

From V10 changelog:
Improved performance when rendering with masks
In cases where the user includes just a small object and the rest of the scene is not rendered we get up to 600% speedup. In non extreme cases it leads to around a 10% speedup

From V11 changelog:
Bucket rendering - improved decision when to revert to random pixel rendering based on render regions and rendering mask.

My suggestion is to update to Corona 11 Hotfix 2 - https://corona-renderer.com/download
Then test your case, and if you are still observing a slowdown, submit a new ticket at https://support.chaos.com/hc/en-us/requests/new

hi team - im still getting that issue when in IR mode, the IR keeps in this motion UNTIL i click off screen (ie another window program) and then IR resumes.  It seems to be with forest pack objects.

Hi, which version of 3ds Max are you using? I am asking this question because we had some similar reports in the past and it always happened with 3ds Max 2022. If you are using this version, one solution would be to update to a newer one.
Also, did it start happening only after you installed a daily build? It never happens with Corona 11 HF2?
Other than that, I can only recommend submitting a new support ticket and sharing the scene with us: https://support.chaos.com/hc/en-us/requests/new

We have a very similar case reported for 3ds Max (Report ID=CMAX-852), but just in case, could you please share your scene with us at https://support.chaos.com/hc/en-us/requests/new

[Max] I need help! / Re: Make an object invisible in rendering but still acts as a solid

« on: 2024-04-18, 11:32:05 »

Hey Maru and thanks for your suggestion :) My aim is to actually block the light casted by the sky on the tree leaves (so they appear less translucent), without the plane casting any shadows to the foreground. I hope I managed to better explain myself here, it's tricky this one :')
I'll check your response on the other post and try it out, much appreciated!

"Blocking the light cast by the sky on the tree leaves" sounds exactly the same as "casting shadow" to me. Sorry, but I don't think there is any other solution.
Adjusting the leaf material, as dj_buckley suggested, sounds like an easier solution.

[Max] I need help! / Re: Black rectangles in saved images

« on: 2024-04-18, 11:27:41 »

Hi guys,

I have been experiencing the same issue for a while. It happened randomly. In the render frame everything is OK but when the render is saved, it has a random sized black rectangle area. It doesn't happen if I save the render as CXR, so I had to save CXR and use copy/paste to photoshop and save the image. I just installed the new hotfix 2, let's see if it solved the issue.

Regards

This should be solved in V11 Hotfix2. If it's still happening there, please contact us at https://support.chaos.com/hc/en-us/requests/new

Work in Progress/Tests / Re: Rendering with Corona

« on: 2024-04-17, 16:51:00 »

Hi, changing smoke color should be pretty straightforward.
You can adjust the absorption color and scale.
Then you can adjust the scattering color. Disabling "single bounce only" can be a good idea to get more realistic results, but it will also render slower.
Here are some screenshots. In the last one I tried setting up some kind of dense, yellowish smoke so I've set both absorption and scattering to a yellowish hue.

Note that if you leave scattering color-less (white/gray) and only set absorption to some strong color, you will get weird results, but it's supposed to work that way. With absorption, you are treating light rays with maths, so the original RGB values may at some point end up as something completely different. :)

[C4D] Bug Reporting / Re: Corona 11 Release dll. crash on Cinema 4D 2024.3.2

« on: 2024-04-17, 16:27:04 »

We can only provide a solution or fix something in Corona if we either reproduce the problem on our end (with a scene or exact reproduction steps) or get an error report/minidump file from which we can conclude what the culprit is. Please see: https://support.chaos.com/hc/en-us/articles/4648898278545-How-to-report-issues-C4D
Also please always share the exact version of Corona you are using. For example "Corona 11" or "Corona 11 Hotfix 1" or "Corona 11 Hotfix 2", etc.

The forum is acting weird and for some reason it did not display your newest posts as unread for me. Super cool stuff as always!
The AI experiment is great too. I understand that some jobs can already be replaced by AI, but for some other ones I am sure AI will stay as an assistant/tool operated by a human. At least for some time... We shall see!

Hi, there was a similar case recently, maybe the solution I suggested would work for you? https://forum.corona-renderer.com/index.php?topic=42411.msg223864#msg223864

Other than that, I do not really understand this part: "block out whatever it would do if it was a normal visible object (Without casting shadows)"
If it would not cast shadows, that would mean that it does not block light. So if it should not block light, then what should it block? :)

Gallery / Re: Kill Bill

« on: 2024-04-17, 15:34:41 »

Hi, please do not take this personally and treat it as constructive critique:

Since the works are "dedicated to Quentin Tarantino" and Kill Bill is the main theme, you should make sure that the poster is not distorted like this: https://forum.corona-renderer.com/index.php?action=dlattach;topic=42487.0;attach=197586;image
It seems correct in this shot: https://forum.corona-renderer.com/index.php?action=dlattach;topic=42487.0;attach=197588;image

[Max] Bug Reporting / Re: Reflections override and Glossiness

« on: 2024-04-17, 15:25:01 »

Hi, this has been reported and discussed before. While it may not seem intuitive, this is the expected result in Corona. Those shadows are caused by material reflectivity. They will disappear if you set IOR to 1.0 for your materials - they will not be reflective any more, but at the same time they will not be realistic. Those shadows are a part of reflection.

If you need to get a reflection override of some bitmap without seeing the "additional" shadows, you can try clamping the HDRI to remove the brightest part from it (aka the sun). See screenshots.

It is also possible that the result you are after can be achieved using some other way. Can you explain why exactly you would like to use the reflections override? We may be able to provide some additional solution or workaround.

[Max] I need help! / Re: Weird IP adress on DR server

« on: 2024-04-17, 15:08:04 »

Since this issue is most likely related to your network setup, I would recommend sending a support ticket here: https://support.chaos.com/hc/en-us/requests/new
Our technical support team should be able to assist you further.

I can also see that there are similar forum threads online (not specifically about Corona though):
https://superuser.com/questions/878351/192-168-1-254-vs-255-dhcp-ip-assignment
https://stackoverflow.com/questions/72502975/what-is-the-difference-between-255-255-255-255-and-local-broadcast-ip
What I think may be happening here is having two subnets (subnetworks) and ideally Corona DR should be used with just a single subnet.
