A camera drone would be cool and would partially solve the issue, but it wouldn't address the very short light radius the Cyclops has when navigating deep, dark tunnels. Sonar or riot!
Just FYI, it is currently IMPOSSIBLE to rotate the moonpool, but there is a way to control its orientation, you just have to plan ahead well. The orientation will be based on the orientation of the FOUNDATION to the base to which the pool is attach…
I really, really hope this is a bug and not a feature. Same thing happened to me on the latest experimental build -- suddenly my fully powered base has no lighting. It's also displaying the water sunshafts inside the base. So annoying.
