How to change PhysicsSignificance from a PartModule in the VAB

[peteletroll]

Because of some NodeRotate issues, I need to activate PhysicsSignificance on some physicsless parts, so that they stay physically significant when launched. Apparently I can't make it work in flight, so I was thinking to make it in the VAB/SPH. Any suggestions on how to make it?

Try PartModule.part.physicalSignificance = PhysicalSignificance.FULL;

You might also have to change PartModule.part.PhysicsSignificance to a different value. 

I'm not sure if the values will carry through to flight, but they should.

Thanks @Benjamin Kerman, further investigation found out that PhysicsSignificance is never specified in the .craft file. I'm afraid I have a problem now 

(clarification: if it's not in the .craft file there's nothing I can do in the VAB/SPH)

You should be able to edit the prefab in the editor but the values may not carry over on scene load

Another thing you could do is have a monobehaviour that checks each part of a vessel on flightscene load and if the physics is off on a part it turns it on

I think setting the value for the Available Part prefab to should work. (0 is full, 1 is none).

part.partInfo.partPrefab.PhysicsSignificance = 0;

That should make any new copies of the part, anything that is spawned in the editor after making that change or anything that is loaded in flight, behave as a normal part.

There is also part.PromoteToPhysicalPart(), you might have to call that on the available part prefab before it works right.

Thanks @DMagic, I'll try this out.

@DMagic, I tried PromoteToPhysicalPart() in flight, but the part detaches from the vessel in a weird way: it falls on the ground, but as soon as i time warp it jumps back into position; then I stop warping and it falls again... Could you please be a little more specific about PromoteToPhysicalPart() usage? I googled a lot, but I wasn't able to find any understandable example...

Found out how to activate physics in flight: after PromoteToPhysicalPart() you have to create a PartJoint to the parent part explicitly. This works when the parent part is physicsless too.

See the forcePhysics() function code for details.

Better forcePhysics() implementation
