Model a membrane

Hi me again...
imagine a zylinder r = 100 , hight = 5
now I want do bend it like a membrane (border does not move)... how to do this?
I tried it with a half sphere, animating G(y)... but this does not work well, because when thickness = 0, particles pass through...
I need a cylinder with some thickness... can you help me again? Thank's Henri

Hi Henri,

Please no new question/themes in an existing forum's thread. Thank you. That helps to keep things searchable.

Here is an example:
CV4_2024_drs_24_MOmb_01.c4d

The shape is based on the Remapping> Contour

Let me know if that works for you.

All the best

Henri,

Here is an updated version based on the image you posted.
CV4_2024_drs_24_MOmb_02.c4d

Cheers

rehello
perfect solution! The capacity is represented by the membrane (her tension is the voltage in my model)
now I will animate the cylinder filed 0... 100 %
please tell me what is the best way to bend in opposite direction ?
ufff... i am such a beginner...
Sorry animate the cylinder filed in the Displacer

Thanks for the extra information, Henri,

Is this working for you?

Hi again... need your help
I used your membrane (03)... perfect... for new orientation, I did put all in a null and rotated it... all good... worked.
Then I pressed something in c4d, and now all my files do not work anymore. For the vertical membrane, the membrane center moves up and down... if I rotate the main null (membrane horizonaly)it works fine again.
I did not find out, what setting in c4d makes this mismatch...
Please give me a hint

1000 grazie! Works!
How is it possible, that it worked before... and suddenly in all files direction was on vertex normal ?
Have a nice day
Henri

[Dr. Sassi]

Great, and thanks, Henri, for the feedback.

Vertex Normal. That is the default. If I had known that you like to rotate those, I would have pointed it out.

All the best

Hi again
this night I woke up and knew what was the problem... I updated to latest version of c4d!
In the old version you could put the membrane in a nul and rotate this... still worked fine (with vertex normal default)...
This changed in last version.

Hi Henri,

I had no idea you were in an older version of this project; that explains it – I assume, as I have no idea in which version you were, even now.

I typically assume the current version is used, and yes, I should have asked for an example file, which allows me to see all that information.

Thanks for solving that mystery.

Cheers

now 2024.2.0... before 2024.1...
buona notte

[Dr. Sassi]

Thank you very much, Henri.

I will keep this in mind.

Buona notte for you as well, it will take a while before I can call it a day.
