New to Vex? You might want to read JoyOfVex first.Still here? Ok then…So you’ve pushed past hscript, ignored python for now, and seen the awesomeness of vops. You’ll also probably start to get curious as to why there’s at least 4 different ways to define point attributes, all with various idosyncrasies. Time to sweep all that away with Vex, specifically with the Wrangle Sop.Wrangle Sops let you write little bits of Vex code, and come with a few UI niceties to make them quick and efficient to use. They come in various flavours (point, prim, detail, attribute), they’re all the same thing, just with the ‘what do i operate on’ menu switched to point/prim/detail.
