Got a report that distant internals were visible when looking out of the planetside (MMSEV) crew tubes. Turns out these are actually windows in hatches, so it would not be appropriate to put a depth mask into the internal space model - the mask needs to be turned off when the hatch is connected.

This could just be a special case of the blocked hatch tech? A: No, because we need the depth mask to be active on EVA hatches as well, which won't be blocked.
