The scene I'm currently working on involves creating a structure similar to the interior of a geode. Think thousands of octahedrons densely packed onto a surface with a Copy Sop which means a lot of overlapping geometry. Does anyone have any idea on how to efficiently boolean these objects to delete out the interior geometry? Every time I try I run into memory allocation issues. I've tried both the standard Boolean SOP and converting to VDB and back to Polygons.

if Boolean SOP itself runs out of memory you can try

- iterating through your pieces within for loop to introduce one piece at a time and Boolean with previous result

- splitting your geo into few smaller clusters, Boolean those individually and then results together into final result

Thanks, I'll try that.
