*** DO NOT BUY - FOR DEVELOPERS ONLY *** Derivable surround that is made to go with my Reflective Dance Club mesh. The center is removed and the surround is placed around the club and does not interfere with the reflective floor. Also has a day/nite sky option that switches on a trigger. Triggers are : day and nite. You can change them to suit you needs. Try before you buy. May not work well with other rooms or meshes.
