Mode: Survival
Mode: SinglePlayer (presumed all)

SEED-ID:Not Seed Specific since it is a vehicle problem.

If applicable:
MODIFIED PLAYFIELDS: NO
Reproducibility: 98% (takes a lot of work to get a valid shape that is complex and works, but what works can and has changed after an update)
Severity: Major but can be considered an edge case

Type: Cargo extensions

Summary: Complex shaped symmetrical Cargo systems doesn't load evenly

Description: Complex shaped cargo systems has the chance to throw the center of mass formula off kilter and have it shift the center of mass off of the center line of the cargo system. Another way to put it is that the center of mass formula gets confused when someone tries to use cargo extensions in place of basic building blocks like steel or wood. Also this happens regardless of the type of container controller used.

Steps to Reproduce: build an hv/sv with using as few standard building blocks as possible and still have the vessel look finished. Load it up with weight and volume on. Enable the show center of mass view in the n debug menu and see that it is off the line of symmetry.

I haven't tried in A10.4 but I noticed it about a week ago (build 2633) and after a few hours of tweaking I had a shape that worked (FBS-MG) but I noticed today that it no longer works. I will go back down to A10.4 and see if the problem is still there. I will update you when I have done that.

[EDIT] I just tried the FBS-MG blueprint in A10.4 and saw the same issue. Before testing said blueprint I spawned it into creative and saved a copy, which in turn removed the red coloring in the blueprint name.

 

[update] After tweaking one of my blueprints that I linked earlier, I found a configuration that doesn't confuse the formula/algorithm. The only difference is that I replaced one carbon block on each side and in the words of Todd Howard "It just works. . ."
In the Pictures and blueprint below I left the new extension blocks unpainted to highlight their location.

Summary: center of mass weird with container extension

So i try to build a basic hauler, but i ran into something a bit annoying with container extension and center of mass. As i suppose, now the items are beeing splitted between the container controller and the container extensions, which is fine, but the split is not even, i mean i run into a situation like this:



So basically i would have understood that the center of mass goes back within the blue axis, but not really the right on the red axis, the volume is not supposed to be fair between the extensions ? so the mass is actually not going into one specific container for heaviest item ? Otherwise the only idea i could have to carry heavy stuff will be to create a container controller with a tower of extension, which limit a lot the designs.

 

Removing the more far away container extensions produced something more expected:
