Looks like "Remove duplicate material" command is internal, I will make it accesible

Here is a new script, which does the work. It's a start point to make selections for Octane plugin materials

Code: Select all

To be completely frank the C4D one never worked for me in 15 years of using C4D.

hmm yes it doesn't work. I never used it. Why you didn't reported this before to Maxon

I've been using the Octane feature for this. It works really great. This whole problem stems only from me trying to access this feature via Python. The feature itself is great and completely negates the need for the native C4D one.

Looks like "Remove duplicate material" command is internal, I will make it accesible

Thanks, you're awesome!

Can I set Live Viewer's Render Region and Film Region using Python? (Button and Region)
You can use Picture Viewer by modifying the render settings.
However, there is no way the live viewer.

There are not any way to change this via script. They are internal and temporal parameters, we don't have no any storage to reveal it. Sorry!

Oh, I see. Thank you for answer

Hi

I have a scripting question for C4D.
I have seen your script to get the Ocane version from the C4D document.

Code: Select all

doc = c4d.documents.GetActiveDocument()
bc = doc[ID_OCTANE_LIVEPLUGIN]
print ("Octane version=",bc[c4d.SET_OCTANE_VERSION])


But the issue is that the document might not show the current version used, it might be a version that was used for the scene before.
Example:
End Customer has C4D 2023+Octane 12 and C4D 2024+Octane 13 installed.
They work with 2023 for their current project.
An artist accidentally opened the scene in Cinema 2024 and saved it.
But then he continues with 2023.

If I request the information from the C4D document in 2023, then it states Octane 13.
Which is wrong.

Is there any way to get an information from the loaded plugin itself?

I stated that I have already tried that script
and it does not work.

Please read my message.
Thanks.

I don't understand your request. You have two different point to read numbers, current plugin version or saved version number in to scene. What do you want to get exactly if scene version number overwritten?
