Instancing in usdskel

Community USD

Following along to this page:
https://openusd.org/release/api/_usd_skel__instancing.html

The attached usd file loads fine but the skelAnimation is not bound to the instances of my skeleton.

Any ideas appreciated.

Cheers,

Martin

Hi @martinc , the only problem with your scene is that USD requires the “root prim” of every Skel-enabled model to have the schemas type SkelRoot. When I changed </Model>'s typeName to “SkelRoot”, then all three instances started to animate - instancing was actually a red herring here, as de-instancing would not have changed the behavior.

Hi Spiff,

Thanks for the reply!
I changed the line:
def Xform “Model” ( to
def SkelRoot “Model” (

Is that what you meant?
Still no animation :frowning:

Hi Spiff,

Just an update. Re-installed USD at the latest version and the above solution you provided is in fact working!

Sorry for the delay and thanks for the help!

Cheers,
