Question about world position offset

[milmarg]

Hi! I have one question about world position offset. I want my bottle actor to break. I'm using vertex color multiplied by texture coordinates to break the bottle. It breaks nice but it's moving mostly in one direction (blue arrow). I want it to move outside (red arrows) from object's center (red dot)

Any suggestions?

multiply it on WorldNormal

I've done this a dozen times, but I'm hitting a mental block and can't remember the setup. Can you be more specific about the solution, maybe include a Material Editor screen shot?
