%%%I am trying to use Blender to make game engine assets. One thing holding me back is the .bullet file export. I believe the issue has been resolved in the Bullet source code. Here is the Bullet bug report showing the issue was fixed:
http://code.google.com/p/bullet/issues/detail?id=618#c15

Now the problem remains to build Blender against a version of Bullet that includes this fix. The process of exporting can be found in the original Bullet forum post:
http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=12&t=8030

Sergej Reich is aware of the issue. Thank you for any help.%%%

%%%I've attached a patch that contains the serialization fix from the linked bug report and increases bullet version.%%%

%%%Sergej, it seems that the same fix was applied on bullet's svn, The thing is that they didn't bump the version yet, so it could lead to some issues? Wouldn't you think fixing issue in btGeneric6DofSpringConstraint.h only would solve the bug for us?

P.S. Seems you've got commit access and i would say commit changes made to btGeneric6DofSpringConstraint is completely fine.%%%

%%%Bullet will only read spring constraints properly when version > 280 so we need to increase the bullet version.
I would also prefer if it would be done upstream an not just in our svn.%%%

%%%This should be fixed by updating the version of Bullet we use, but that will have to wait until after release. Assigning to Sergej so he wont forget.%%%
