Thanks Jim. That’s exactly what I thought I could do, because the space I have modeled needs different lighting to illustrate each of two different perspective viewports on my layout, I thought I could set up a View Mode for each light, just as you suggest. Sorry the below is long, but there’s a lot of failure to recount, with a lot of settings.
First I set up 2 lights, each creating the shadows desired for one of my two different viewports. But in Options>ViewModes>“ViewModeName”>LightingScheme>LightingMethod, “Default Lighting” and “Custom Lighting” result in shadows that don’t match the ones I’ve created and don’t respond to any movement of the lights. Only “SceneLighting” creates a view mode that will accurately reproduce these shadows, but only from both lights at the same time - I’ve found no way to deactivate only one light in any one viewport: Any settings in the Lights tab affect both viewports, and any settings referring to viewport-specific layer activation or light selection in the tabs affect only the display of the individual light objects, not the presence of the shadows the lights cast.
All these settings seemed to offer Viewmode-specific and/or Viewport-specific controls of which lights are active, but it seems that they don’t.
Either a) I’m missing something, b) there is no way to do this, or c) something’s not working properly.
