VU Meter out of clone grid and sound effector
Hello everyone,
I’m working on a sort of Audio Meter type animation/transition where I’m trying to control the visibility of clones in a grid so that they behave as a VU meter would.
It’s easy enough to create some cubes, clone them and control their y scale with the sound effector, but that’s not the look i’m after.
I’ve gone through Mylennium’s tutorial on this site regarding a similar technique, however, it doesn’t apply to a clone grid, rather just one linear cloner. i can replicate his effect over the entire cloner (using the shader effector/filter shader) to drive the visibility of all of the clones at once, but the problem is that each row of clones reacts the same way, losing the “frequency” effect of a VU meter.
anyone have any suggestions to help point me in the right direction? I know I could just create one linear cloner and duplicate several times applying a different frequency filter to each copy, but it seems like there would be a more efficient way to accomplish that task.
Anyway, as always, any help would be appreciated!
Thanks so much!

Unfortunately I don’t see a really easy way to do it. The only way I could think of was via Xpresso, and since the mograph>effector node doesn’t seem to work with iteration nodes, I had to duplicate the setup for each bar. I did set it up so you can control the frequency range with one condition node which could be used with user data to automate it a *little* bit, but not entirely satisfying.
Here’s the file: https://www.3danvil.com/tutorials/VU_Meter.zip
You could do something similar using a shader or step effector to control visibility, but you’d have the same problem in terms of manual setup.

Hey Adam,
Thanks so much for your response, I kept messing around with it just in xpresso and came to the same conclusion that it would have to be individual instances.
However, i Did figure out a workaround. i went into after effects and rendered out a grayscale video of VU meters I created using sound keys and some expressions and then used that as a texture in C4D. I applied that texture to a Shader Effector and flipped on the visibility and bingo!
I can still use a plain effector to do some fun wipe on wipe off effects as well.
anyway, wanted to say thanks and let you know what i came up with!
I’ll try and post my result when i’m done!
Thanks again!
