VEX vs VOPs in General Houdini Questions Posted July 31, 2017 I wanna use VOPs whenever possible. Looking at lines and lines of coding is such a buzzkill for me. Absolutely hate programming/debugging. All I want is a beautiful result; and as a non-programmer; I was very attracted to Houdini specifically because of VOPs. It really turns me down to see Houdini users opting for VEX over VOPs.
