History

#1 Updated by gamerprogrammer almost 8 years ago

I made minimal craft that crashes. Then I reattached unmanned command module and crash gone. I've reattached it to same part.

So the tree of parts should be same, perhaps there is an error in its generation - i've changed root node many times when I was building my craft. Also I used subassemblies.

Craft files are in attachment. Also subassemblies (the problem was in STS-MTUG.craft).

Hope it helps.

Hi gamerprogrammer, this is a known issue with the TR-38-D decoupler on OSX, though the cause is unknown.

It is the only decoupler with PhysicsSignificance = 1 (turning off physics) to make large craft less wobbly.

Changing this to PhysicsSignificance = 0 will prevent the issue.

You can find this in GameData/Squad/Parts/Structural/Size3Decoupler/part.cfg
