Editor Properties: (see get_editor_property/set_editor_property)

  • apical_dominance (float): [Read-Write] Strength of tip-driven lateral bud suppression.

    High = single dominant leader (pines, firs). Low = freely-branching, bushy structure (shrubs). Bud activation requires ApicalHormone < (1 - ApicalDominance).

  • auxin_falloff (float): [Read-Write] How quickly auxin concentration drops with distance from the tip.

    0 = uniform auxin throughout the branch (very strong suppression everywhere). Higher = auxin only suppresses buds near the tip, with lateral buds further down free to activate. Controls the spatial pattern of apical dominance.

  • min_gravitational_dot (float): [Read-Write] deprecated: Use FPVGrowerGravityParams::MinGravitationalDot instead.

  • radical_auxin (float): [Read-Write] Base level of root-zone auxin.

    When > 0.05, suppresses axillary sprouting near the base of the plant (mimics the natural suppression of below-ground side shoots). Useful for preventing low branches on tree trunks.
