Hey all, after seeing lots and lots of similar questions on a few Houdini discords about how to vary copies in the Copy SOP, I wrote a terribly long explanation of how to manipulate orientation and instancing using template attributes, matrices, for-each loops, compile blocks, and some other tricks with packed disk primitives, with a .hip file at the end. Might help some newer or intermediate users. Post is here: www.toadstorm.com/blog/?p=493
