I am working with the Quadruped rig trying to assign it to my dog model.
I am following the Quadruped Auto Rig Tool tutorial, and everything goes well until I get to the deform rig.
The tutorial has me go into the deformation rig's Skin object and assign the file source. But every time I do, I get an invalid group error in the lower nodes. It does not like the rightside group.
And after that none of the muscle painting functions work like the tutorial says they should.
I've tried re-creating the nodes, changing the names, copying the nodes from the tutorial files, and nothing works.
I realize that the tutorial was done on a much earlier version but it seems to work well until this particular point.
Anybody know what I'm missing here?
Thanks!

its a know bug,
the gruping is incorrect, that something you will have to fix by yourself.

the frist group is grabing prims in +X

then converting the points to prims and here is where the issue happen, the original group is not done using the points, was created with prims

so when it convert the groups you have to revert that.

Thank you for your help.
I was ready to give up on Houdini, now I'm back on it.

I got it to work but only partially.
It still has a warning about the leftside group and it will not hide the one side, which makes it very difficult to paint the different muscles.

I think I need to learn how to make my own rig, this one is way too complicated for my model.
I'm looking for a tutorial on working with bones in Houdini - it is a much simpler process in Blender.

Thank you again for your help.

that group happen for the same reason
beacuse that group doesnt exist

you need to follow the nodes, i dont have houdini here to check it, i think the group is trying to read is points, so you need to change it to primitives, or the other way around.
