I own a mainland region where I am starting to rent houses. My neighbors who own adjacent regions to mine have "For Rent" and other signs that hover in the sky at levels between about 250 and 350 meters. I wanted to do the same with a "Homes For Rent" mid-air sign. I purchased a set of mesh letters, resized them (32x32), and made them transparent except for the top face. I hung them at 300 meters. Now I have a very distinct shadow of each letter on the ground. I don't see shadows on my neighbors ground from their mid-air signs. What do I need to do to get my letters to not cast shadows on the ground? Thanks!
