There was a problem hiding this comment. can this fail? if so maybe we need to add validation on the evaluation and reporting that error occured.

There was a problem hiding this comment. (answer offline) the only thing that can fail is if the CC isnt present or the path isnt a component path - but this function documents expecting a valid component path - and this is made sure of before calling into this one. So any such error would be reported from "above" |

There was a problem hiding this comment. Not for now, but I think we should eventually refactor all those Python functions into a "helper" sub-module of usd_component_creator and avoid redefining and reparsing these functions all the time. (Merged with Anthon's) |
