Hello @ELJeffery,
Welcome to the Maxon developers forum and its community, it is great to have you with us!
Getting StartedBefore creating your next postings, we would recommend making yourself accustomed with our forum and support procedures. You did not do anything wrong, we point all new users to these rules.
Forum Overview: Provides a broad overview of the fundamental structure and rules of this forum, such as the purpose of the different sub-forums or the fact that we will ban users who engage in hate speech or harassment. Support Procedures: Provides a more in detail overview of how we provide technical support for APIs here. This topic will tell you how to ask good questions and limits of our technical support. Forum Features: Provides an overview of the technical features of this forum, such as Markdown markup or file uploads.It is strongly recommended to read the first two topics carefully, especially the section Support Procedures: Asking Questions.
About your First QuestionPlease have a look at Support Procedures: How to Ask Questions, specifically in the context of repeatability. We cannot run your code as it is not executable as it is lacking things like imports and also some logic, e.g. adjust_uvs. Otherwise answering your question is pure guess work for us. Please also explain in one to two sentences what you want to achieve. "Updating" uv data is a very broad term. Until there some clarity and executable code, that is unfortunately all I can say.
Cheers,
Ferdinand
