Hello,My problem is that I make a light on Inventor Studio the light beam goes through every object. I have defined materials for my objects but no change. The material is aluminum. I can see the light beam on the surface but I can also see it other side of the object. What might be a problem?I also would want to know that is it possible to make a light which beam is 40 degrees times 30 degrees?Thanks for replies.- käyttäjä
