Constrain 'Push Apart' to specific axis

[DaveMDarcy]

Hi All,

How can I make Push Apart work on just x and y and not z for example?

I have a Voronoi Fracture that is breaking up nicely just how I want it using Push Apart however it is also pushing the pieces upwards as well which I don't want. In other words if you imagine a flat plane breaking apart, I want it to only break apart along that plane, not in height also, I'm sure I must be missing something simple.

Kind Regards
Dave

Hi Dave,

There is no option, as the pieces of the Voronoi Fracture often don't allow for a simple push apart along one axis.

Please have a look at the version with the Weight Selection. It is a manual try, so add weight or (Alt/option for subtract) to move the pieces in one direction. Doing so gives you a result, but it becomes quickly clear where the problems appear.

Hi Dr Sassi,

Thanks very much for the swift reply, this would be perfect if only I could get it to separate along z as well

Kind Regards
