Hahah, the fun thing is: just use your background image!
No need for extra HDRs!
The only culprit is when you use reflective material like gold, Glas, anything which is reflecting HDR so that you can see it. Then the wrapped poles could be visible. But on your starship it will work like a Charme. Promised.

The last six, seven picture were lit with the same picture I used for background. You can probably see it in the water heart the mushroom offers the mushrooms lady. The poles are wrapped. Nomad just use anything and wrap it around a sphere to light your scene. Just awesome easy.
