Getting the offset of MoGraph clones

rui_mac

I'm trying to get the position of MoGraph clones (in my case, from a Matrix object) that has a Random effector that randomises the positions of the clones.
However, the list that I get from md.GetArray(c4d.MODATA_MATRIX) always returns the original position of the clones, not the position that is the result of the Random effector.
I'm coding inside a Python effector (that is AFTER the Random effector, in the Object Manager).
So, how can I get the position of the clones AFTER they are adjusted by the Random effector?
Thank you very much in advance.

Hi,

Could you follow our forum guidelines? Please use the tag and mark your thread as a question.
Using tags, you could have provided your c4d version and language (python in that case but it's not always obvious)

Could you please share a scene to reproduce the issue because I'm not able to reproduce the issue? In both parameter and full control mode, my python effector retrieves the modified position.

Could you provide the c4d version you are using?

Cheers,
Manuel

@m_magalhaes , I tried to edit the post but it told me that I can only do it until one hour after posting

The file I include creates a Matrix with 20x20 clones and randomises their positions.
Then, a Python effector reads the positions of all the clones and adds their indexes and distances to a list, if their distances are less than a threshold amount.
However, the distance that is stored is always the same, as all the clones were evenly distributed and not randomly placed.
I'm using r20.

Hi @rui_mac ,

the order of your effectors matters, you have the Python effector before the Random effector in your file, and then your Python effector will of course retrieve the 'vanilla' MoData of the matrix. The gif below demonstrates the effect. Does the order have no effect for you? Your file came at least in the incorrect order, with the Python effector being evaluated first.

@ferdinand, YES!!!
That solved it. Thank you so much.
Forgot about the effectors order inside the Matrix. I was only changing the order in the Object Manager.

Hello @rui_mac,

without any further questions or replies, we will consider this thread as solved by Monday the 20th and flag it accordingly.

Thank you for your understanding,
