How does the welcomeAboard library node work?

[woosh]

In Blender 2.79 you have the option to enable textured solid, in the viewport shading panel


For the black in the transparent texture: it's simply because the mesh has a material applied (which changes nothing for the export) it makes the transparent parts black. You can either remove the material, or enable transparency to make the transparent parts appear transparent.

Right, I had no idea about any of that! Thank you!
