I managed to find this on the forum.. But I'm still having trouble using the attribute transfer. I don't know which node to use from the muscle_capture.. Can someone help me please!

Moin,
you have to transfer the capture data from the body to the cloths. I am attaching an over-simplified example with a smaller tube inside (“body”) and a larger tube outside (“cloth”).
The idea is that the originally captured object has an attribute on its points that “weights” the respective point to position changes of the attached bone. If you want to attach another geometry to the same bone, all you have to do is “copy” this weight over by using an attribute transfer node and add a deformer that uses this attribute to deform the secondary geometry.
Maybe this helps?

Hello, here is what is happening.
1.I am using muscle capture (metaballs) for the body.
2.I have added a capture layer paint node just after the weight switch.
3.I have transferred that node to the clothes with object merge and attribute transfer.
4.Then I get this message that says obj/muscle is not a valid source.

Hi, Almina,
without being able to look at your file, I am clueless.
The error messages indicate that you are referencing objects that don't exist at the given path (like Matthias said). I have to admit that I am a non-noodle-type of guy, I really can't do with nodal “programming”, it takes me 10-20 times longer to understand a node-setup than seeing the same thing in the typical 2-3 lines of code.
So I don't even know *what* you are trying to attribute-transfer.
Did you have a look at the sample file I created for you? Did you understand what was going on in there? If so, I would *think* that transferring that idea to your setup should work without errors. In the end, you'd just be binding some point-deformation to the same weight as the original (body) points, straight forward.
If you don't want to provide a (simplified, readable) version of your rig, maybe you could do a screencast where you show how you set up each (important) node, including the attributes you created?
The best solution, though, would probably be if you tried to achieve your goal with a blank project, simplified geometry and rig and *understand* what you are doing, then redo it in the complex scenario of your rig. “Try to crawl before attempting a home run” …

Hi,
in your simplified version you need to adjust the capture regions (they are too small, they don't enclose the actual geometry). To do this, use “Edit Capture Region” from the Rigging-Shelf, then select one of the bones, press enter and adjust the size of the capture region using the little black arrows.
Second, do not delete the capture attribute. Go to your deform node and deselect “Delete Capture Attributes”.
That should get your simplified version running correctly - and you can take it from there
Marc
P.S. Just saw the video (well “seeing” … let's call it: I had a vague vision ). I don't see a deform node on the cloth object. Possible that I missed it, but are you sure you followed the examples above?

Okay I managed to run the simplified version correctly. Thank you malbrecht
But I can't apply it to the version with the model and clothes in it..
Maybe muscle is more difficult? I tried to understand what is going on in the muscles.hip file but still having a hard time…

Maybe you have misunderstood the muscle deformer
and the capture layer paint:
http://the-final.com/houdini/Capture_Layer_Paint.mp4 [the-final.com]
now video with klicks and keyboard + better Muscle deformer attached
For muscles and rigging this (is not only old) helpy:

For Character animation have also a look here:
https://www.sidefx.com/forum/topic/34936/ [sidefx.com]
the great Tension Map Example from Werner Ziemerink.
And have a look at the deltamush deformer, too.

(not houdini, should only explain deltamush)
