Advice on Projection Surface
If we get this right, it will remain in place (not sail away) & provide an incredible visual experience in extreme weather environments, later this summer. Need the best material (shade cloth, muslin) for projections on two opposite surfaces. (50 & 40' high)
On one, light can go through.
On the main one, it can not as there will also be projections in the interior. 3 other sides of each covered in light shade cloth. The side taking the external projections can be hit with powerful projectors.
