Hi, this is fixed in R21.1 SP1. Cheers, Maxime.

@m_magalhaes said in Error after hitting Undo.: i just scratch a bit your code, but i've discovered that with the R21, MCOMMAND_SPLIT only return true. I've opened a bug entry for that. this is fixed in R21.1

@m_adam After installing v2.6.48 c4dpy works fine.

Thanks s_bach very much.

While the bug is still there I set the topic as solved. I will bump the topic once the fix is in a release. Cheers, Maxime

@s_bach Thank you.

Thanks everyone. The purpose of me is export model from revit to cinema 4d. I choose other way. Thanks you very much.

Hey Guys! I think I figured it out! Will resoond if there's any questions! Cheers! MattG

Hi @orestiskon SendModelingCommand and especially CurrentStateToObject need the object to be actually in the passed document. So you need to create a temporary doc and use it to operates. As bellow: import c4d def currentState(obj) : return c4d.utils.SendModelingCommand(c4d.MCOMMAND_CURRENTSTATETOOBJECT,[obj],c4d.MODELINGCOMMANDMODE_ALL,c4d.BaseContainer(),obj.GetDocument())[0] def main(): # Retrieve the python generator obj = op.GetDown() if obj is None: return objClone = obj.GetClone() if objClone is None: raise RuntimeError("Failed to clone the object") # Make the children Python Generator disapear obj.Touch() # Creates a temporary document that will be used to evaluate the cache of the object tempDoc = c4d.documents.BaseDocument() if tempDoc is None: raise RuntimeError("Failed to create a temporary doc") # Inserts the child python generator that exists only in memory into our tempo doc tempDoc.InsertObject(objClone) returnedObj = currentState(objClone) return currentState(objClone) Cheers, Maxime.

Hello Maxime, thanks for your answer! Its too bad that I can't do it without some hacky way, but thanks for your code snipped and example. I'll mark this thread as solved, so thanks! Best Regards, Florian

As @zipit this is a rough quick estimation and could be wrong. If you want more information I suggest you use external libraries like psutil see https://stackoverflow.com/a/11615673. Cheers, Maxime

The problem is solved. It was so trivial :D. I unchecked the plugins folder which I added in the preferences. My plugins folder was in the C4D directory, so as you described, it was loaded twice. Leaning for me: Never place a custom plugins folder in the C4D directory! Recommendation to the SDK team: Maybe you could adjust the error message in the console, which mentions that plugin folders should not be in the C4D directory. I would assume that many users/ devs will place the folder there, because of a habit from older versions. Thank you @r_gigante and @zipit for your quick response!

I just figured out the answer - I needed to disable "Optimize Cache" on the generator's Object tab.

I did that for the same reason @m_adam created a copy in his version: A node can only be member of one document at a time and also only be inserted exactly one time into the same document (long way of saying that Cinema is monohierachical). Cheers zipit

I think we are talking past each other. You can of course build any project any way you like. An then make sure that your plugins link to the build result using the link options defined in projectdefinition.txt. But I think you want to include an already existing (non-plugin) project in the solution created by the Project Tool, right? And I think that is not possible. I guess you could add the project manually to the solution created by the Project Tool.

Thanks for the response. I changed my code to match the example you gave and it seems like that fixes the immediate problem I was running into. It will take some tests to verify if this covers all of the circumstances that I need it to. I appreciate the help. John Thomas

Thanks for the great suggestions! I just discovered I can also use "File | Save Object Preset" and "File | Load Object Preset" in the Attribute Manager.

Hi pyr, thanks for reaching out us. Consider that the Scale modifier operates on the transformation matrix of the object when in Object Mode, whilst it operates on the parameters specified as lengths when in Model Mode. Finally, as pointed out by @zipit, providing more context will be definitively beneficial since with a very simple example I'm not able to replicate the issue as well. Best, R

Hello Maxime, thanks for that detailed answer. Much appreciated. I see, drawing slows down things massively. (3minutes vs. a few seconds) Bad luck for me then. But it still helped me though, I'm now going for another approach. (The GUI part was just for convenience, so everything is fine) Thank you and cheers, Robert

Thanks Maxime! In the mean time I will cycle through takes, AOVs and Frames manually to get the paths.
