I’m trying to use the RuntimeMeshComponent Plugin ( GitHub - TriAxis-Games/RealtimeMeshComponent: Unreal Engine 4 plugin component for rendering runtime generated content. ) in a project, and subsequently package it for Linux. I have my Cross-Compile toolchain and everything set up, but there seem to be some specific errors during packaging that I don’t know enough about to try and troubleshoot.
Not excited about having to throw out the plugin, as I spent the better part of a week integrating everything. 
Thanks for any help that can be mustered!
