Great, both worked.
It seems to be no speed difference between both methods.
In the IPR quicktest the tyCache method seemed a tiny tiny bit more smooth, but here I'm speaking just about details when zooming in, that will maybe nobody see.
(anyway a IPR is maybe no good test
The tyMesher is quite handy, when working with multiple tyCaches in the same scene.
