Nested IDL meshes, as seen in a modeler (Silo).  The solid-looking innermost mesh (red truncated cone) is the visible light mesh.  It fits very closely over the navigation light part of the existing model (John Hoagland's Viper MkII).  The dark shadowy bubble surrounding is the aura mesh.  and just outside is the unseen IDL emitter (yellow wireframe).  Note the softly curved shape of the aura (the dark transparent shadow mesh), because of the double edge blend node's sensitivity to shape.  Click image to enlarge.

     I also made VisLight, aura, and emitter props for the cockpit monitor and engine exhaust...

.     If John Hoagland gives permission, I'll release this IDL prop set as a smart-propped P9+ accessory for his Viper model (you'll need to have his Viper model).
