Thanks guys.
The bridge name comes from the big part of the object that is in the middle.
The old test image below shows the concept more clearly.
The object is more detailed and the planets etc. are a little different now (and still changing).
The feeling it gives is right when you haven't seen the model in full light Ulco.
So not sure if i will use the POV of the spherical image. But just as another image it could stay of course.
I kitbashed the model from some small parts and it is full 3D with some small texture displacements added.
The model is in two parts and is 1-2 GB in size.
When you put a reflection shader on the object and then water with reflection on the planet
you get these awful long render times unfortunately. With glass it would take 1-2 months probably

The lights on the model is a texture map with luminosity.
