I'm new to Houdini and loving it so far but there is one thing that absolutely stumps me. I'm sure for someone advanced this might seem silly but:
1. How do you fracture only PART of an object instead of the whole? I've tried the voronoi fracture points etc, I've set the fracture radius very small and still everything breaks apart. What I need is something like a bullet hitting a wall - the whole wall shouldn't crumble when that happens
I'm sure I'm missing something extremely simple but I just can't figure it out. If somebody can point me in the right direction I'd be very grateful.
Use the voronoi fracture points sop as second input for voronoi fracture sop and turn on clustering, and use metaball(s) to define impact position for voronoi fracture points sop.
Cut your object up using a bunch of different techniques. It could be as simple as the Break shelf tool on the Model shelf tab to cleave your object up and then fracture the part you want. You can create your own cutter with another manifold (closed watertight) object and use the Cookie boolean SOP.
The attached file switches between a Break SOP and a Cookie SOP.
Btw the Break SOP uses Cookie inside so arguably both use booleans.
