Code: 

MotionState::MotionState(object *_object) : m_pObject(object){float x = m_pObject->getPosition().x;float y = m_pObject->getPosition().y;float z = m_pObject->getPosition().z;float qx = m_pObject->getRotation().q.x;float qy = m_pObject->getRotation().q.y;float qz = m_pObject->getRotation().q.z;float qw = m_pObject->getRotation().q.w;btTransform transform;transform.setIdentity();transform.setOrigin({ x, y, z });transform.setRotation({ qx, qy, qz, qw });m_Pos1 = transform;}
The above code does not display the objects and crashes when I advance the physics.
The code worked (objects showed and moved) when I didnt set the rotation (ie I just set the origin or location).
How would I go about setting the initial rotation of the object? I am using motionstates and read in one of the manuals this was the way to do it, but I can't figure out how to set the rotation.
