I have made a node network that generates a terrain from a map. I displaced the points in a point VOP and need the height of this. For basic geometry I can use $SIZEY for this but in this case it is not recognized by Houdini or just returns 0. I figured the $SIZEY does not work for everything, but don't understand where I can or can't use it.
Anyone who can help me out?

Cheers!

Hello.
For getting better information about whether this is work or not please check geometry spreadsheet.
Houdini can't really show per point created attribute in just a little box this is why spreadsheet is alive.
Regards.

if you open docs for each node, you should see which local variables it supports, if any

but generally you can use expressions like bbox() or centroid() to replicate that functionality in nodes that don't support them

Try the getbbox functions in the new point sop:

Exactly what I need!
Thank you for the response, this will help me a lot!

Cheers!
