Problem: I want a nice soft look to my lighting, but can't seem to get it. Is it possible?
Not really. The currently-available technology for softening or blurring the edges of the light would simply overload FrameForge’s processing speed, making real-time work all but impossible.
That said, you can emulate light diffusion to some extent by adjusting the Shadow Darkness setting in the Lights dialog: drag the slider to the right to make shadows darker (harsher), left to decrease their opacity. The latter will simulate the look of diffusing a light.
