Important Note
-
There is a noteworthy change in how UFE paths should be called in Maya 2025.3+ related to the normally hidden "world" node in Maya. The change (only in Maya 2025.3+) is to unconditionally add "world" (hidden Maya root node) as a prefix to Ufe paths. Previously the code would only add the prefix "world" if the path wasn't prefixed by "world".
-
Use of
str(ufe.Path)should be avoided asstrwas only meant as a debugging tool. Instead useufe.PathString.string(ufe.Path). Examples:
Use:ufe.PathString.string(ufe.Path(pathSegment))instead ofstr(pathSegment)
Use:ufe.PathString.string(path)instead ofstr(path)
