Only draw entity you are in or that are docked.

[JinM]

I recently had to do some logic and rail stuff, and the rail moving entity got stuck or wouldnt move.

Sometimes it is because the server has an error with the colission checking, but sometimes it is because I blocked the way with some accidentally placed block.

It would really help to check for such accidentally placed blocks to activate an option, that only docked entities are shown, or the other way around. Or maybe have them drawn transparent.

In cases where I can afford the space, I will place blast door on the mother entity as a shell all around the moving part, so that if there are any troubles, I just "open" the blast door shell, and can see around. Usually, just opening the shell a few times will be enough to allow the part to move again.
