I’m currently trying to analyze a ray bounce using grasshopper and ladybug. I’ve got my location set up properly using an EPW file. I’ve also got all the sun vectors I’m interested in. I’m using only the first sun vector at first, I can check the other ones later.
When I try to use the Bounce From Surface tool, I do get a list of Bounce points and they are drawn on my sourceSrf, but all my rays receive a null value and no rays are drawn. Does anyone know why ladybug won’t draw any rays in this case?
