I would like get a simple explanation how to add natural light for a interior rendering.I am an interior designer and need to show details on my renderings.I don’t want to use the artifitial light all the time.please tell me if I have to add a plugin extension or there is some editing option after the rendering is ready ( inside Fluidray) to add brightness.Thanks.
