New IsaacSim 4.5.0 urdf importer not allowing dashes ("-") in mesh file names

[Simplychenable]

there’s been others who ran into this issue as well; feels like it might be design as intended and not an oversight? let’s see what the devs say

URDF to USD Converter error

This error message indicates that in a USD (Universal Scene Description) file, the path “base_link-base_link_inertia” is not a valid way to reference a specific part of the model, because USD paths should use underscores (“_”) instead of hyphens (“-”) to separate elements; therefore, the system is automatically changing it to “base_link_base_link_inertia” to make it a valid path.
