MountObject

I am playing with mountObject(), but I found in ShapeBase class, if it's mounted to other object, it didn't really related itself to the the object it mounted to. I only find in StaticShape::processTick() :

void StaticShape::processTick(const Move* move)
{
Parent::processTick(move);
...

if (isMounted()) {
MatrixF mat;
mMount.object->getMountTransform(mMount.node,&mat);
Parent::setTransform(mat);
Parent::setRenderTransform(mat);
}
}

I think this should be be put into ShapBase::processTick(), Do I make sense? Can I simply move this part into ShapeBase or I need also to do other works?

I also have another problem with exporting the mount node from 3dMax with the plugin which I downloaded the proper version from this website,I simply cloned two nodes from hub0 and hub1 node, and named them Mount0 and Mount1, but after export to .dts, I coundn't find my Mount0 and Mount1 node, does anybody knows what's wrong?

Thanks for feedback!
