I’ve noticed three issues with using the lights with Rhino 6’s default Renderer.
1.) When using the physical light objects from the Lights menu (such as the Spot Light and Rectangular Light), they create shadows on the ground and have a small effect on the model in the Raytraced viewport shading mode, but they have no visible effect on the model when you actually hit Render. Similarly, they have no effect at all in the Rendered viewport shading mode.
2.) When using Rendered viewport shading mode and experimenting with Backdrop and Lighting, I noticed that the Custom Environment for Skylighting works just fine on Rendered and Raytraced viewports, when you hit Render they don’t do anything.
3.) The Ambient Light option only seems to change the colour of the ground plane.
Are these problems anyone else is seeing?
