Well, in making of this car demo, 
https://www.youtube.com/watch?v=zCBESbHSR1k we simply exported the 
submeshes we needed explicit control over as separate obj files and 
loaded each one usign a Mesh component aggregated to an Entity. Each 
Entity has it's own Transform component that we then bind properties to 
QML expressions that reference the Qt Quick Controls, e.g. slider values 
or boolean switches.

You can also have all meshes in a single OBJ file and reference the sub 
mesh you wish to render in the Mesh component. We tried this but found 
it to be better to split them out as it allows more work to be done in 
parallel at start up, leading to faster startup times.

Cheers,

Sean
