G'day mrmacca

nice work!!!

I recon you should light it first unless you already know what your camera shot is gona be.

if you light it you may decide a different camera shot or sequence.

then again if you allready have a shot in mind you can use the lights specificaly for that shot.

I think I just succesfuly worte in a circle, sorry about that bro.

nice pipes, any power cables or small pipes branching off?
