Hi,
I need help to make this work ?

ej; box > color 1 > color 2 > blend shapes.

my idea is translation changes from one side to another color as prefabricating a random colors, is it possible ?
with a KeyFrame would be easy to change in blend shapes !

or maybe the reel should be a bit more longer ?

my idea is to make with “attribute from map” a random of images with “blend shapes” for example this expression
sin($F)

and not vary objects with “blend shapes” because that's not my idea.

please help.

you might try a Switch SOP instead of the blendshapes SOP

thank you Michael, I already come to do work blendshapes with colors and imagens : )
