Using the bricker option of Divide sop to get subdivisions in a single axis is really slow for high resolution meshes. Why? Is there a faster alternative?

Roll an attribute cyclically using the remap node and feed it into the clip node.

Thanks, this works but seems to require a decent amount of subdivision to begin with. I'd still be interested in a method that doesn't.

Python verbs can call SOP nodes several times:

Performance-wise the boolean node with a bunch of grids might be faster, though.

Hi,

You can also do this using a C++ Wrangle (inlinecpp Python module [www.sidefx.com]). I used it in production a lot of times and the speed was orders of magnitude faster than other methods I have tried.

Thank you both, I'll try the different options.
