Houdini's built-in Resample COP only does Stretch. If you want a letterboxed fit, a fill that crops to the canvas edge, or a tiled repeat with mirroring, you're chaining nodes and computing UV offsets by hand — and redoing that math every time a resolution changes. If you want to resize by a reference image's resolution you need to add another node to the mix.

Scale COP is a free HDA that wraps the whole thing in one node. Pick a target resolution, choose a fit mode, optionally tile, pick a filter. Done. No manual offset math.

Fit modes: Distort, Fit (letterbox), Fill (crop to fill), Width, Height, None (1:1 pixel)
Tile modes: None, Repeat, Mirror X, Mirror Y, Mirror Both (with UV offset)
Filters: Point, Bilinear, Box, Bartlett, Catmull-Rom, Mitchell, B-Spline, Auto
Size reference input: connect any upstream node to drive the output resolution automatically — no manual width/height entry when your canvas size changes

Houdini 20+, any edition. FX users: a build script is included so you can compile the HDA under your own license and avoid the Indie/Apprentice flag.

First Houdini release from Funkworks — a small open-source collection of free DCC tools built from real workflow problems. Feedback and bug reports welcome.

Awesome, that did it!
So straightforward. Thank you so much

Sometimes I need to write out a sequence of geo, but each step is bottle necked. My CPUs never get over 6%.

How would I pipe this into a TOP network or TOP Geometry SOP to write out the geo?

I get that PDGs are super powerful, but for me they'd be most useful as a parallelizer.
