Try this

Code: Select all

doc: c4d.documents.BaseDocument  # The active document
op: Optional[c4d.BaseObject]  # The active object, None if unselected

def main() -> None:

        c4d.EventAdd()

Thank you for the answer Aoktar!

I've tried the code you provided, it works if Octane has been activated before, but not on a default c4d, i think it has something to do with the Octane Init and activation, i have attached a video showing the different behaviors. The point of this script is for my studio's pipeline to be able to initialize scenes renderer depending on the project

Delete line 20! It's not hard to find errors if you check the messages

It was indeed line 22 that was causing errors! Thanks for pointing out that error, i know it's not that "hard" but as i am a beginner in python and dev, the error was not really understandable from the console. That's why i came here for help

Understand, I forgot this trial line. I've thought to add undo at moment. I think it's OK?

Yes now it works even if Octane has not been activated/initialized thank you very much!

1. Is there a way to get the selected nodes in Node Editor via python?
I want to do some operations on the nodes that are selected by user

Also, I know GetDown() can get the FIRST child node, but
2. how can I get the subsequent child nodes?

Thank you

Hi, I am using python script to create a OSL texture node and load the OSL script from external file.
I am able to set these two parameters. But it seems the OSL do not compile and the parameters for the OSL script donot show up. How can I press the Reset&Compile button and Glsl->Osl button via python script?
Thank you

Example script from reading the Octane preferences

Is there way to change compression only for textures that have "diffuse" in their name for example ? Unfortunately change compression globally for selected textures in Octane Texture Manager is not possible for many of them selected - it ask for every texture.
