I downloaded DAZ Studio 4.8 late last night and did my first scene this morning. (My first try at 3D since using Poser 2 briefly many, many years ago)

I set up two spot lights as the only light sources hoping for a high-contrast render. In the Viewport pane it looked right; high contrast dramatic lighting, with one of the spots having a red color.

When I rendered (NVIDIA Iray) the lighting was very flat, bland and dark, and the red coloration of the main spot wasn't evident. Is the viewport pane more contrasty than the final render as a rule? Do I need to exaggerator any effects in viewpoet? Or am I just doing something wrong?

Any suggestions would be deeply appreciated.
