Ok, found the issue. I expected each input to actually have a value, but this was incorrect - some can have a node reference instead. Thanks for reporting, a PR is coming with a fix.
A note about the babylon log node - the namespace is now BABYLON, name of node is “flow/log” (which I hope we can somehow normalize, with different namespaces).
the result is interesting -
Is this still a work in progress, or was this expected to work already? Need to know if I am doing something wrong in world space.
