Hi.

Do anybody know how can I change my fragmentaction type using shatter node in Houdini? I mean, I'm trying to apply this effect to objects and then in some parts add more fragments. thanks!!!!

More points = more fragmented shards.

One way you can get more points on a location, when working on a 2d type object is to create a dense grid or shape to match the object and paint it based on where you want more points, and then scatter points based on that attribute.

The other way is if your object is in 3d, you can convert it to an fog object using iso offset, and with a volume ramp or volume vop, you can create areas of more density, and then scatter the points using that density.
