Spaceships naturally have no gravity (well unless spinning or accelerating). I'm not in the pre - alpha to know how this is being handled in any ship that a person is not sitting in, i.e. big enough to walk around in.
So I'm proposing gravity plating (maybe as a technology) that a builder places on any surface designed to be the 'ground' within the space vehicle. This will allow walking within an open area of a ship, as well as vertical 'transport tubes', which would be lined on all sides with gravity plating to create zero gravity within the tube.
It may also help the dev team in linking avatars within a ship - last thing anyone wants is a ship to accelerate leaving all the non seated avatars floating in space.... or worse.... crushed against a bulkhead o.O
Anyway, thats my 2c, hope Im not suggesting something that has already been suggested lol
