Sorry for late respond but i would like to explain my request. My whole object (screen_01) contains only few pieces of geometry. It was made before mascros
But to do this i have some complicated tree (screen_02) - some generators are repeted because i cant use from-->to range (i can do conditionals for each segment but it is time consuming and complicate generators - fastest way is copy generators for desired mat. ID)
Even if i use xform each segment has same starting point in UV space - so if i drag point on spline i got visible repetitons (screen_03)
Now if i apply UV mapping for whole object modifier ignore previous UV's and i have desired effect - even if i change element lenght (generator in scale mode) i have still proper mapping (screen_05) because starting point for each element is in same place in UV space (screen_04).
I hope it sounds logical:)
