Hello everyone, I have found an alternative material for the ramps and the surfaces that are not centrally irradiated by the projector.
The material is not as dark as Black Diamond is a shade of gray. Darkstar 9 is not available in Germany and also in larger quantities worldwide to my knowledge.
As soon as I clarified how I can get the new second projector film in the required amount, I will contact you again .
Cheers,
Benjamin
