the geometry has growth fluid animation, thus the topology changed by frame.

that's great tips bellow, but geometry that topology changed by frame by frame, does not work well.

the geometry does not have outer/inner surface group.
if that has the groups, i can recognise inner or outer by it has the group with VEX.

thanks

thanks,
but the method does not work well on my case.
I found other method in procedural.


1)Connectivity
- Connectivity Type: Primitive

2)foreachBlock
-PieceAttribute=class
vdbFromPolygons
-surface

3)vdbCombine
-FlattenAllA
-SDF_Union

4)convertvdb
-toPolygons
