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

« on: Today at 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: Today at 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

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: Yesterday at 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: Yesterday at 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: Yesterday at 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: Yesterday at 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.

[Max] I need help! / Re: Invisible to camera but obscuring everything hidden by this object.

« on: Yesterday at 13:50:28 »

I think I have managed to get what you need. :)
Create a Corona Legacy Material (because it's easier to get non-physical properties with it, such as lack of reflections).
Set its refraction to 1 and IOR to 1. That should make it "invisible".
Under advanced options set alpha to "always black".
Then plug a Corona Rayswtich Map into this material's refraction color and make it GI - black, reflect - black, refract - white, direct - white.

It should also work with the Corona Physical Mtl somehow, but I haven't tried it.

[Max] Bug Reporting / Re: Clicking on Corona bitmap "load bitmap" doesn't work

« on: Yesterday at 13:06:51 »

Hi, if it wasn't working globally, we would have a lot of user reports. :)
Most importantly, please try updating to Corona 11 HF2 - https://corona-renderer.com/download
Even if something is broken in Corona 9, we definitely won't be fixing it there.

[Max] Daily Builds / Re: Chaos Corona 12 for 3ds Max - Daily Builds Discussion

The crash was caused by the 3ds Max Chamfer modifier and, according to our investigation, was not related to Corona at all.

Hi guys,

I have a similar issue with Corona 11.

Here is my topic.
https://forum.corona-renderer.com/index.php?topic=41611.msg219991#msg219991

On Friday I submitted my note to Chaos Help Center. I've still waiting for any response.

Can you share your ticket number? I could not find anything under your forum email address.


For Misshurika the ticket number was #226825 and the issue was related to overheating. The system stopped crashing after undervolting the CPU which lowered the CPU temperatures from 90+ to ~75C.

Please note that Corona cannot directly cause a system crash. It can cause a 3ds Max crash, but if the whole system crashes (e.g. a blue screen or restart), that would point to things like hardware or driver problems.

« on: 2024-04-15, 17:30:48 »

For a fully invisible material, try using an empty Corona Rayswitch Material. It should not affect any effects in any way. Let us know here if it doesn't work.
