# Description

With Isaac Sim 2023.1.1, the main asset file stores all the meshes as
well (even for instanceable case) when using the URDF improter. However,
the referenced paths to materials are absolute which does not allow
moving the asset around freely. This MR adds a fix to make sure all
paths are relative in the converted USD file.
