# Quick Tip 8: How to select each nth element in cloner

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) )`
