First of all congratulation for your work!!!!!looks very intense.

The problem that I have is with BulletSharp...I Export with Blender Generic6DofConstraint and I try to read the limit in serializeDemo with the method GetConstraintByIndex(0).
Seems like the Upcast in Generic6DofConstraint doesn't work,instead HingeConstraint work properly can you Help me with the wrapper?
I want to convert constraint in my Blender project into FeatherStone constraint.

Thanks in advance!
