In this short video i will show you how to select each nth element in cloner and make smooth interpolation between them.
2 formulas from video:
Without falloff: if( mod(id;f) == 0; 1; 0)
With falloff: if( mod(id;f) == 0; 1; if( mod(id;f) < (f/2); f/2-mod(id;f) ; mod(id;f/2) )/(f/2) )
Also you could find example file on my site http://philipppavlov.com/quick-tip-8-how-to-select-each-nth-element-in-cloner/
