Modifier for values of F-Curve

active

F-Curve Modifier is the one being edited

Type:boolean, default False
blend_in

Number of frames from start frame for influence to take effect

Type:float in [-inf, inf], default 0.0
blend_out

Number of frames from end frame for influence to fade out

Type:float in [-inf, inf], default 0.0
frame_end

Frame that modifier’s influence ends (if Restrict Frame Range is in use)

Type:float in [-inf, inf], default 0.0
frame_start

Frame that modifier’s influence starts (if Restrict Frame Range is in use)

Type:float in [-inf, inf], default 0.0
influence

Amount of influence F-Curve Modifier will have when not fading in/out

Type:float in [0, 1], default 1.0
is_valid

F-Curve Modifier has invalid settings and will not be evaluated

Type:boolean, default False, (readonly)
mute

F-Curve Modifier will not be evaluated

Type:boolean, default False
show_expanded

F-Curve Modifier’s panel is expanded in UI

Type:boolean, default False
type

F-Curve Modifier Type

  • NULL Invalid.
  • GENERATOR Generator, Generate a curve using a factorized or expanded polynomial.
  • FNGENERATOR Built-In Function, Generate a curve using standard math functions such as sin and cos.
  • ENVELOPE Envelope, Reshape F-Curve values - e.g. change amplitude of movements.
  • CYCLES Cycles, Cyclic extend/repeat keyframe sequence.
  • NOISE Noise, Add pseudo-random noise on top of F-Curves.
  • PYTHON Python.
  • LIMITS Limits, Restrict maximum and minimum values of F-Curve.
  • STEPPED Stepped Interpolation, Snap values to nearest grid-step - e.g. for a stop-motion look.
Type:enum in [‘NULL’, ‘GENERATOR’, ‘FNGENERATOR’, ‘ENVELOPE’, ‘CYCLES’, ‘NOISE’, ‘PYTHON’, ‘LIMITS’, ‘STEPPED’], default ‘NULL’, (readonly)
use_influence

F-Curve Modifier’s effects will be tempered by a default factor

Type:boolean, default False
use_restricted_range

F-Curve Modifier is only applied for the specified frame range to help mask off effects in order to chain them

Type:boolean, default False
