Fracture object and time offset in Effector not working

[vincent.hardy]

Hello,

I have been trying to get a project working with the MoGraph Fracture object so that I can apply effectors to geometry I generate through a Python Script. This works awesome for effectors impacting the position / scale / rotation of the fracture object children. However, I am not able to get an effector to properly impact the children's time offset.
In the attached file, I have tried to isolate and illustrate the issue with a simple test case:

• In green, I have a simple cloner which has a Random Effector. The Random Effector sets a random 0-20 frame delay (the effector min is 0%, max is 100%). As expected, the clone's animations (a simple 90 degree rotation) happens at random times.
• In red, I have a fracture object with the same number of cubes, at the same positions as in the cloner (for comparison). I have set the same Random Effector. However, there is no time offset applied to the fracture object's children.

Am I doing something wrong, is this a bug or working as expected? If working as expected, what are my options to set a time offset for each of the fracture object's children, if effectors and time offsets do not work?

Including my test file:
fracture-time-offset-question.c4d

Thanks in advance!

Hi contribution-stage,

Thank you very much for the file!

Use a Cloner instead while having the Object>Reset Coordinates switched off and set to linear, with no PSR change. The number of the Child objects should match to get the time as expected.

Then the Cloner will work for your setup with objects such as Fracture Object but provides the needed "cloning process" that the Fracture object does not show.

CV4_2025_drs_25_MGcf_01.c4d

In my understanding, the Fracture sees a Child as a single Clone, even if there is an ID number that tells otherwise…

Please let me know if that works for you.

Cheers

Hi Dr Sassi,
Thanks a lot for the prompt answer, and yes, this works perfectly for me.
Much appreciated!
