There are three types of variation you can play with separately in the breeder: numerical, color, and 3D object variation.

▪        Numerical variation determines how much numerical parameters vary during breeding: stem lengths, leaf sizes, percentages of plant biomass1UCKPV3 allocated to different parts, growth rates, and so on. Numerical variation produces different plant forms.

▪        Color variation changes the colors of plant parts randomly when you breed.

▪        3D object variation randomly pulls 3D objects from the current 3D object library and places them on breeder plants. 


You can change how much of each type variation is introduced during breeding by choosing menu options or clicking on the breeder toolbar buttons.

To turn color variation on or off,

▪        Choose Vary Colors from the breeder Options menu, or click the Vary colors button on the breeder toolbar.

To turn 3D object variation on or off,

▪        Choose Vary 3D Objects from the breeder Options menu, or click the Vary 3D objects button on the breeder toolbar.

To set numerical variation to a predefined setting,

▪        Choose one of the menu items in the breeder Options menu (Vary Numbers > None, Low, Medium, or High). Or click one of the numerical variation buttons on the breeder toolbar, thus:

Vary numbers none 

Vary numbers low 

Vary numbers medium 

Vary numbers high 

▪        The None choice adds no mutation; the Low choice produces 20% mutation; the Medium choice produces 60% mutation; and the High choice produces 100% mutation.

To set your own breeding options for numerical variation,

▪        Choose Vary Numbers > Custom from the breeder Options menu (or click the Vary numbers custom button on the breeder toolbar) and make your choices in the Breeding and Time Series Options window that appears. 

▪        The items below explain how to change specific items in the Breeding and Time Series Options window. You can customize breeding by changing the strength of mutation, the blending mix between two breeding parents, and how the breeder handles non-numeric parameters like yes/no parameters.
