[Max] Bug Reporting / Re: How many times Corona, how many times?? (Quad menu issue)

« on: 2025-06-20, 16:39:50 »

Hi, I can understand your frustration, but the answer is simply that there are no news regarding this yet. We do have it logged, but please note that we have lots of bugreports and feature requests, and we need to carefully prioritize them. Even if something makes it to our roadmap, there is no guarantee that it will make into the release. See: https://trello.com/c/7s5cmRFA/272-important-road-map-information-please-read

Also, this isn't something commonly reported by our users. If there are others, who would like to see this improved, please be vocal about it. The more messages we see from our users, the higher the chance that this will be improved in the future.

Sorry for putting it bluntly, but we have limited time and manpower, so we will never be able to make everyone happy, immediately.

« on: 2025-06-20, 16:31:15 »

Sorry, but currently applying the AI Enhancer to LightMix isn't possible. As a workaround, you can use the >Scene button in LightMix to bake LightMix values into scene lights. Please note that this isn't non-destructive so you may want to save a backup of your scene before doing this if you are planning to adjust LightMix further.

[Scatter] Cinema 4D - Bug Reporting / Re: Scatter C4D splines + Render Spline Tag

« on: 2025-06-20, 15:58:29 »

I guess it should work, unless there are some technical limitations.
It's logged as (Report ID=CC4D-1041).

[C4D] General Discussion / Re: Outline Material

« on: 2025-06-20, 15:39:20 »

I made a hollow cube and clipped through it. Do I understand correctly that in a case like this you would like the outline to be drawn at the visible edges of the object? More or less like in the attached screenshot?
Can you explain how exactly you are using this setup?

[Max] General Discussion / Re: AI enhancer and interactive virtual tours

« on: 2025-06-20, 15:10:29 »

I did the following:
- set up a simple scene
- add the AiEnhancer render element
- add a Corona camera with spherical projection
- set resolution to 2:1 ratio
- render
- submit to Cloud using the AI Enhancer button
- it resulted with an image that was marked as a panorama
- used the enhance option
- it resulted in an enhanced image that is still considered a panorama

So the panorama + AI combination seems to be working fine. Can you explain if you did something differently?

[C4D] General Discussion / Re: Strange situation with Corona Render! Cinema 4D is very difficult to open!

« on: 2025-06-20, 15:00:01 »

I had a similar problem and opening Cinema 4D hung at around 65% loading plugins. It was at a time that i was using my Chaos licence between home and work on idifferent PCs, so I manually started the Chaos Licence Server whenever I changed PC and it seemed to speed up the loading.

Hi, do you mean starting the License Server from the Start menu did the trick? Or how would you start it?

we have the same on bigger scenes, but here it is related to file search paths, lic server is running.

turn them off when opening a corona scene and it opens fast, then after open you can turn them on again.
it seems something corona(and maybe vray) does wrong with the search paths at opening. rendering works fast and fine though,

it must be some problem at star when it tried togenerated the previews or editor shading(only my guess)

What exactly do you mean by file search paths? Could you tell me where to find this setting?

[Max] Bug Reporting / Re: Corona Pattern Bug

« on: 2025-06-20, 14:53:31 »

Regarding the on/off map - this is currently the expected behavior. We split the object into "only pattern is visible" vs "only the base is visible". To "fix" it, you can assign an invisible material to the base object and use another one for the pattern. Corona Physical Mtl or Legacy Mtl with 100% transparency should do the trick.
Note: don't use the Rayswitch Mtl as it seems to crash (this is now reported).

Regarding U & V rotation - please log it at the Ideas Portal - https://chaoscorona.ideas.aha.io/

[C4D] General Discussion / Re: Phoenix simulations

« on: 2025-06-20, 14:15:58 »

You can export a Phoenix simulation to the VDB format and import it into Corona for C4D using the Corona Volume Grid object. Other than that, there is no Phoenix for Cinema 4D.

If you would like to request some new Corona features, you can do it here: https://chaoscorona.ideas.aha.io/

[C4D] General Discussion / Re: How to get Corona version with Python?

« on: 2025-06-20, 13:57:02 »

I am primarily a 3ds Max user so I don't know anything about Python in C4D, but I asked ChatGPT and it looks like it gave me a working code.
Just copy-paste into the Script Manager, hit Execute, and check your Console (Shift+F10 by default) for the printed Corona version:

Code: [Select]

import c4d

def main():
    # The “world” container holds all of C4D’s global settings.
    world = c4d.GetWorldContainerInstance()
    # Corona’s prefs are stored in a sub‐container under ID 1030480
    coronaPrefs = world[1030480]
    # Read the core version preference
    version = coronaPrefs[c4d.PREF_CORONA_CORE_VERSION]
    # Print it to the Console
    print(f"Corona for Cinema 4D version: {version}")

if __name__ == "__main__":
    main()

Looks like it used the information from https://forum.corona-renderer.com/index.php?topic=37328.0

You can just drag-and-drop a CXR into the Corona VFB.

[Max] I need help! / Re: Rug rendering

« on: 2025-06-20, 10:28:45 »

You can use a map to drive instance height. Tooltip under the "map" says that blue is for Z axis, so we need that.

Alternatively, you could use the new Scatter feature Clusters > Instance color to map. This way you can scatter taller strands on color 1 and shorter strands on color 2.

[C4D] General Discussion / Re: Falloff alternate in C4D

« on: 2025-06-20, 09:28:52 »

Not sure what exact shader can be used in C4D, but in Max I would use the Falloff as a mask inside a Mix node.

I think AI-enhancing LightMix makes perfect sense so I have logged it as (Report ID=CMAX-1724).
