Hi, is there anyone already worked with retro-reflective materials? We want to simulate them however, I assume that energy plus (simulation engine) considers only specular reflection and thus thinking if there is anything else that I'm missing when creating a retroflecting radiance material. Thank you for your tour time! Maria
