replace low res geo with high res

[ldotchopz]

Doing a ball simulation and trying to replace the low res spheres with high res sphere models. I thought this could be done by using a birth flow and flow update, and change the shape to high res, but the birth flow event shows the high res spheres for the first frame and then changes to the original low res spheres after the first frame of animation.

Is there something i am missing?

Thanks
