Multithreaded bullet + moving a ghostobject = WTF

[Granyte]

Trying to move a ghost object to the position of a rigidbody seem create a preatty wierd result when using multithreaded bullet.
Look at this video.

Basicaly every spinning object is linked to a rigidbody and a ghostobject and when i try to move the ghostobject to the rigidbody position the rigidbody goes spinning around out of control.

I looked at all my code and i boiled this down to these 3 lines of codes when i disable them the problem goes away but when they are enable i get this issue.
Also this issue does not apear when using single threaded bullet.

Code: Select all

btTransform newtransform = ghostObject->getWorldTransform();
		newtransform.setOrigin(myRigidBody->getCenterOfMassPosition());
		ghostObject->setWorldTransform(newtransform);

What is your platform ?
In my own experience, Bullet multithread does not seems to work properly on windows 64bit platforms...
