Using saved data from "In_Editor" function?

I’m currently cooking/saving data from a native UE4 “In-Editor” function to an external binary file so that I can use the generated data in-engine.

There is no technical or legal reason that I should not do this, is there?

Never had to get so deep into the source code before, and just wondering what the best practice is.


If you want more specifics:
I am using the USkeletalMesh->GetSourceModel() function to get access to the vertex positions and normals of a given Skeletal Mesh.
Other functions (non In_Editor) that returned this data were either too slow, or returned unpaired and/or garbage data.

(Note to Mods: I was unsure which board this would be better suited to, so I also posted this in the “Engine Source” board. If you need me to delete one or the other please let me know.)
