Completely agree APART from the spells obviously. I have been using vops all the time and now am starting to think I should learn some more basic vex code for wrangles. When I have seen more experienced working I see how they could be really useful. On the other hand vop networks (the ones like ICE, people say vopsop as thats the old name) are very clear whats going if someone else was to pick it up.?
To have the option is the best bit! Morten as I said I looking to do some more vex, I found this, looks handy, Im sure there are many others, the docs are quite good too https://sites.google.com/site/fujitarium/Houdini/sop/wrangle On Tue, 8 Nov 2016 at 09:41 Morten Bartholdy <[email protected]> wrote: > Thanks for the advice Gerbrand, it is much appreciated.
