Here is a setup for the Capybara Configure Guide Deform LOP using the SOP setup from the shelf tool that is optimised to prevent guide weights being recalculated each frame, as well as preventing cross-contamination of attributes between the prims.

Sorry you experienced this problem. The solution is to place a Rest SOP on your skin too, so between the "capy_skin" and "bonedeform" nodes. The attribute copy that you have in your guide stream is unnecessary as those values are being carried through. It would only be necessary if you had cached out your simulation and didn't want to resimulate after adding those attributes upstream.

Not having an error on the LOP for the missing rest attribute is an oversight on our part - we will add that. Once the rest attribute is there though, the slow lagginess goes away and the procedural becomes really fast again.

We will also take a look at the documentation again and see if we can add anything to make this process clearer.

I wouldn't use the buttons in the simulation itself, rather deform them to the cloth afterwards. If you're in H21 or later, then you can use Surface Deform to deform the buttons, and turn on the Blur toggle and crank the Blurring Iterations and Step Size to maximum to preserve the shape. If you're in an earlier version of Houdini, or if the Surface Deform doesn't preserve the shape rigidly enough, you can use Guide Deform with the Geometry to Deform set to "Arbitrary Geometry" and then toggle on "Rigidly Transform Pieces".
