Importing parts of an FBX file through Shotgrid Loader

Hello all!

I’m currently working to implement some custom hooks in the Shotgrid Loader such that a user can import from an FBX file just the skeletal mesh, or just the static mesh, etc. I sort of have this working, but I am running into an issue where if they attempt to load in a different part of the FBX file after having first loaded in an initial part, it acts as if it is loading into Unreal, and then nothing in the Content Browser changes. For example, if they loaded in the Skeletal Mesh, but then wished to also load in the materials, this does not work. No errors, either. I have the “replace_existing” flag set to be True, but this does not seem to have any effect and I am not sure why. Is my goal simply not possible? Is there a setting I am unaware of that I will also need to set?

Any help would be greatly appreciated!
