No, there isn't currently any option to modify this.

I tried to reduce this problem somewhat by having a kind of double-ended light. If you draw a sphere, you can see that half of the sphere is not black, there is a front lit part, and the opposite side of that is also lit, with a band of dark only around the middle.

This helps keep things from getting too totally dark, but it can still be a problem in some models and at some angles.

I eventually do want to have it set up so you can switch between several different lighting options, but probably there will just be the current one for the V1 release.
