I would love to see an option where a component can be selected to not cast shadows, or at minimum, not effect the light of any particular source, like if you had an IES spotlight, you could bypass any component from affecting the dispersion. Example below is a Tech Lighting/Visual comfort fixture that has an IES file which behaves exactly how their fixture would, however, if you have an actual model of the fixture in the scene, the resulting light pattern is horribly wrong, because the geometry of the fixture interferes with the IES file.
Does anyone have an idea of how to accomplish this in the meantime?
