i was doing a “mirror” to my rig,
the Kin Chops where able to get the mirror, they didn't create a new node on the scene, they mirror inside the chop node.

the muscles where also able to get the mirror, but the only thing i couldn't get was the blend pose i did for the foot, is that something that i have to redo on the other side, or is possible to mirror that?.

Yeah, the blendposes don't get mirrored. You can probably do it manually by copy/pasting the CHOP setup and fixing the paths. Finally, the source and target pose values will need to be mirrored as well. Unfortunately, this last step isn't always well defined. If you're just dealing with world space values, you can probably just negate the tx values.

will be nice feature to mirror the blends,
and also when mirror the bones that they mirror the nodes position base on its parent .

thanks edward.

It does as far as I recall. ie. the bones are mirrored to their parents. I forget the behaviour when you select multiple parts of bone chains though.
