Thanks for the feedback! Will experiment with the ambient occlusion, but the excess shadowing was deliberate. I was experimenting with some kind of door markings but haven't found anything decent, designations is a good idea. Full unload is deliberate, but a fixed relative position instead of fixed cylinder position makes sense. Will also tweak the puzzle to make it a bit clearer on what to do. And the hook only a puzzle item, not a weapon - going to make what it clearer what can be used as what.
