Hi Oliver, it's looking really great!

> Would be lovely, Michael, if the lamp position could be adjusted.

In MoI v2 check out the lighting options under Options > View > Lighting options - if you want more light overall, try the "Lighting style: Key + more fill" option which is brighter, or use the custom levels options to tweak the levels individually.

It's usually better to switch those options to increase overall brightness if you want to reduce dark areas, rather than messing with the light direction.

But it is possible to adjust the direction of the primary fill light by a script though. For that you need to set up a keyboard shortcut and put the script from here on it:

That script will switch the light direction between the default direction and an alternate direction on every keypress.
