anyone know about the reverse foot preset breaking again in 21?

when using reverse foot after ikfk blend, and blended to fk mode, if i rotate the knee or ankle the toe doesnt follow properly. This is very similar to a bug in 20.5 that was patched and seems to be back in 21.

I'm getting these errors which pertain to my APEX node stream within my hda after I blackbox my custom apex hda. I have been doing tests for weeks making blackboxed versions of the same hda, suddenly it started giving these error chains that pertain to many of my apex autorig components

basically, the HDA has no issues until I try to blackbox the asset, houdini crashes, and when i restart houdini and load the newly generated black boxed hda, it throws a chain or those NameError:'s Component Source and SnippetSource

Anyone got any idea what it could be?


heres what they look like

All these kind of NameError:'s mention SnippetSource and ComponentSource

i saw this change log from May on houdinis website

"20.5.614
Fixed a bug in APEX Script resulting in the default values for callbacks added by apex script being unexpectedly cleared.

Thu. May 29, 2025"

I'm trying this on the daily build of 20.5.641 and its still not working. Not even sure if that change log is even related to this.

This is really cool thank you so much for sharing!

I was wondering how to get the cartoony eye setup in apex. I checked your example and a couple questions I have is how do you pack this up for apex stream. And also how do you bind the lattice to joints in the skeleton as you mentioned, should I just use the tet embded to biharmonic bone capture workflow for that?

I haven't seen an example of the apex invoke graph being used before so I think that's why I'm struggling to figure out how to pack it properly for apex. As seen in the picture attachment I inserted, I tried doing it with pack folder node like I normally would but I feel like I'm way off.
