Thanks for pointing that out!
Anyway, I've added a multiplier to determin the scale of the "Bulb", a diferent clamp node to reduce the ugly effects at the edges and ran some extra renders with a new set-up. First, without stretch, then with outward stretch anbd finaly with inward stretch. The TGD file is set for inward stretch. Juist go to the X and Z displacement nodes and change the multiplier from 1 to -1 to get the outward stretch.
