We found a good workaround! We now made a custom commandline plugin where we can add our own arguments. And it works great. If anybody in the future has this issue you can always contact us and we will help.

Thanks again everybody for all the help!

Hi Maxime,

Thank you for the response, we are trying out a few others methods now. :) There is not much confidential, it just comes down to our current queue manager software and workflow methods here, and with that this option from Zipit is not ideal.

Thank you very much for all the support guys, I will update this post when we know more.

Stay safe!

This is exactly what I also need, only just for Python.

Thanks Zipit and PluginStudent,

@PluginStudent I already use the Pluginmessage function, see example below.

def PluginMessage(id, data):
	if id == c4d.C4DPL_COMMANDLINEARGS:
		argstring = ' '.join(sys.argv)
		if "- customsubs" in argstring:
			CommandRenderChangesomething(sys.argv)

	return True

But than you have the problem that is not running before the -render command just like you said. It all about the order of operations I think. Cinema needs to wait until the script is done before starting the render.

@zipit Very interesting and something to look at. I already have another workaround. I can set a RenderDocument function in the script. Meaning I will do everything from the script. Making the adjustments and also the rendering. Skipping the whole -render.

But I like to do it with the method above for many reason to long to explain:D Something like this must be possible right? Or maybe not

Hi All!

I'm trying to run a python script before running a command line render. For example, change the subdivisions of a scene before you render the project.

The problem is the order of operations. The example below doesn't work.

The custom script is called -customsubs and works with the C4DPL_COMMANDLINEARGS function.

"C:\Program Files\MAXON\Cinema 4D R21\Commandline.exe" -render%userprofile%\Desktop\test.c4d -frame 0 0 -oimage %userprofile%\Desktop\test -omultipass %userprofile%\Desktop\test_mp -oformat TIFF -customsubs

I found a user with a similar problem but he is using C++ and this method of priorities is not working with python as far as I know.
Link to user with same problem

So the questions is: How can I run a custom python script before the -render command?

Thanks you!:)

Did some testing, it seems there is a bug with the intersection selection. It does not work correctly when you enable "hide new lines" previously this was working.

In the file I added you can see the incorrect intersection. If you turn off hide new lines it seems to work again. But this was previously working with this option turned on.

Hopefully Maxon can fix this issue.

Hi mp5gosu & Andreas,

Thanks for the help! This should do the trick!

I need to convert this to Python, since I don't know C++, should start learning that soon.

Any help with this would be awesome of course!

And thanks for the change to the new workflow, will keep this in mind!:)

Hi!

For our render plugin we like to read in the C4D console at startup. In there is information about plugin version for example that we can cross-reference.

Is there a way to access these lines? Or export it.

In R20 there is new feature to export the console, that can be very useful. Only problem is that it only exports new lines.

Hopefully there is another way to do this?:)

All tips are welcome!
