3ds max 2020 Lighting Creating photometric lights . That’s optional. The light doesn’t have shadows enabled yet, so we won’t see them. We can go directly to the lights modify panel and then enable shadows. Shadows on. And it’ll take a moment to update, but now we’re seeing shadows in our view ports. Alright, that’s how to add a photometric light to the scene. . I’m going to change this up. I want a more linear curve here. So I’ll set the high lights to a value of point one five, the mid tones, to a value of point five five and the shadows, a value of zero. So now I have a fairly neutral response curve to the camera exposure control. So, that’s how to set exposure control for the physical camera and, in this case, also the perspective view.
