Hello!
I need to light up some objects in my scene and do not light other objects. It's easy to do using include/exclude option in Corona lights. But problem in my case is that objects excluded from the lighting of Corona lights still cast shadows from these lights. Attached picture explains problem better than words. As you can see, sphere is excluded from lighting, but still cast shadows to the floor. Is it possible somehow to get rid off this shadow using Corona lights?
In Vray, for example, if the object excluded from illumination and shadow casting it doesn't cast shadow. Vray lights used in Corona give the same result as Corona lights - no lighting, but shadows are on picture. Mental ray's lights do the trick, but get a lot of noise to the picture, so it's not the solution.
Another option would be switch off shadow casting in object's properties or use CoronaRaySwitchMtl, but I need these object to cast shadows from other lights in my scene, so this is not the solution as well.
I would be grateful if you share your ideas how to solve this problem.
