Creative mode. Single player. Large grid build. Problem: Large ship of battlecruiser size cannot be brought to a stand still in space. It will slowly accelerate into one direction (sidewards, to larboard, if there is also a pull to another direction added, I don't know) and this happens also with shut off engines. When they are engaged, exhaust flames occur on the side of the ship which is the direction of the pull. I have read so far that sub grids may be the reason for troublesome weight distribution or center of mass calculation, something in that style. And you should override thrusters to compensate for this. Is this correct? I don't seem to get a positive result when trying to fix that pull to one side, it's not even clear after some tinkering if thrusters of opposite direction or of same direction like the pull have to counter it. This pull is so strong that my basic ion thrusters won't stop it from accelerating the ship. I have to switch on separate thruster systems (much stronger ones) to get it close to a stand still, but 0,3 m/sec are always happening, no matter how many are firing. Yes, there are several piston-operated platforms on board and a couple of rotors. These have been switched off, to no avail. Question: How to fix? By thruster finetuning or is there a script for automated, immobile idling? If standard dampering fails? Goal: (primary) Making ship immobile when no propulsion is engaged. (secondary) Or at least kept at a place with help of thrusters successfully countering the pull.
