@ferdinand Thank you very much for your reply and responsiveness!

@ferdinand Yes, of course you can. And thanks for the answers. I'll be waiting for news.

@ferdinand Thanks again for your reply.
I've done everything you asked. A clear pattern has emerged: the program crashes when the geometry in the Boolean is modified.

• As soon as I remove the Python tag (which completely affects the geometry change) and one node in Xpresso that affects the geometry (the noise in the displace modifier), everything works correctly.

• If I leave only Xpresso with the node for changing the noise in the Displace modifier, the program crashes.

• If I remove the cloner in object mode from the new Boolean from the setup, the entire setup with its programming tags works correct.

• If I replace the new Boolean with a legacy Boolean and subtract the cloner(in the connect generator) from the main geometry , the entire setup works correctly, but the geometry is cut poorly.

• If I remove the automatic code, but animate the cloner's position and angle changes using the Vibrate tag, the program crashes during playback.

My conclusion:

1. The new Boolean breaks the program when, with random cloner positions and angles, the geometry is cut incorrectly (there were cases where the Boolean simply returned empty geometry), crashing the program.

2. Or the problem is with my computer, but I didn't have such problems before until the new Boolean was added to the setup.

@ferdinand Thank you very much for your reply. I currently have the latest version of the program (screenshot).

The program crashes when the cloner is in object mode (circle spline) with cubes placed inside a new Boolean and subtracted from the main geometry( 1st object under boolean).

Reproduction:
1. Open project in Cinema 4D.
2. I play the timeline and after a couple of seconds the program crashes.
3. I restart the program and the project. I remove the nested Boolean objects one by one (Sweep, Cube, and Cloner with Cubes).
4. Deleting the cloner in object mode (a spline circle) with cubes inside solves the crash problem.

Result:
1. Program crashes

Versions:
NOK 2026.0, Windows 11

@ferdinand I just now noticed that the file attached incorrectly. At the time of publication, it's 6:00 PM(time of crash cinema 5:57PM), October 18th, Vladivostok time (UTC+10 (GMT+10)). The program crashes on random seed values. Am I correct in understanding that I can't change material parameter values ​​using the Python tag?

@ferdinand Thanks for the reply. I'll keep that in mind.

Hi. Why does the Python tag or Python node in Xpresso crash Cinema 4D and how can I fix it?

I created a crystal generator project where I use the Python tag to randomly assign generator and spline parameters, and use the Python node in Xpresso to assign the Redshift material(Crystall 1) parameter values ​​(I can't access these parameters via the Python tag). Certain SEED values ​​("Кристалл 1" user data) crash Cinema 4D.

@m_adam I still don't understand how to get the id of parameters? How do I know that this parameter has id 500?

@i_mazlov Thank you for your reply. That was very helpful!

Hello again, everyone. I still can't figure out how I can use a button in a tag using python. I need to select two points and fix them in a tag. Can you tell me the correct solution? Use Python Generator.

@ferdinand How nice to know there are professionals like you out there. Thank you for your help, it is encouraging to keep going. Optimized and Works as it should!

@ferdinand I'm sorry, for some reason I didn't realize I had to put the code in right away. Thanks for your help, I will study the code! I'll let you know what happens.

Hey, everybody. The code aligns my objects along the direction of the spline, but the problem is that the corner of the original meshes, do not look along the spline. I have tried c4d.utils.MatrixRotY() and other axes, but I don't get the rotation I want. I feel I can solve this problem somewhere in the green area(screenshot). Is there any solution to this problem? And to have the last object rotated 180 degrees relative to the others. The second screenshot is as it should be.

@Cairyn @Kantronin Hey, everybody. Could you throw a more detailed implementation code?

@ferdinand Just ran into the same problem. Thank you for the solution!

@i_mazlov I tried the GetRad() method. This is exactly what I need, thanks!

@i_mazlov Hi, thanks for the reply! My situation is like in the screenshot. I have a parametric spline and text that the spline should fit to. I guess I'm interested in local coordinates, although global ones would be useful. There is no code. I just saw how they do it through xpresso, but it looks complicated.

Hello everyone, what code or function can help me achieve this task? As the text changed, the rectangular spline changed its size according to the bounding box.

@ferdinand Thank you very much for the expanded object.

Hello everyone, I want to make a script that will align an object with wronged axes using the "Align Workplane to Selection" command. But the problem is that I don't understand how to access the coordinate manager so that I can use it to reset all values in world coordinate mode. Tell me, how can I achieve this? Screenshot example:
