Create a space dome

Good evening everybody

I tried to create a space dome.
I see a lot of tutos to learn how to do a photo mapped dome but the result is wrong in all cases.

The photo is multiplied on all faces of the dome instead projected.
What I do wrong ?

I can’t upload the SKP file because is bigger than 16mb.

Thanks for all your advices.

Also check this extension:

Might do what you need.

Make sure the flat version is set to ‘Projected’ (rightclick > Texture) and than sample it (hit ‘B’ then hold the Alt key to turn the cursor into a pipet, sample by clicking on the flat, let go of the Alt key and click on the dome)

Thanks for your help.
