Still new to Houdini, but I ran into something interesting(for me) when I was trying to just take the idea of deleting particles based on their Y value. This seemed to work fine until I turned my points into solids.
When I was using points, in my dop network I used a geometry wrangle node with the following condition to kill particles below a certain Y value: if(@P.y<-.25) removepoint(0, @ptnum);
Now, when I try this with baked geometry that has been converted to solids and using a finite element solver, I can't seem to get the same results. This is where I'm lost. I'm assuming, it's because the solids are now no longer points. But I don't know how to access them for deletion.
I attached a file with a simple setup if you're curious to take a look. I'm just taking the idea of deleting objects based on Y height and applying it across the board with all solver/object types.
Any help is much appreciated!
Best,
Stark
