Hlsl nub

what is the hlsl equivalent of the map node set to wrap ?

also, “max” with more than 2 values ? (sort+cdr)

if you don’t find apropriate intrinsics (that are supported by vvvv) you have to code your own functions.

your first task may be coded with lerp and a modulo i guess

now that you mentioned it, frac is good enough by itself.
im using it for luma shift
