softness property

double get softness

World-space penumbra radius for this catcher's shadow, decoupled from the scene's shadow settings.

0 (the default) inherits the scene's DirectionalLight.shadowSoftness. In live mode a positive value overrides the softness for this catcher's draws only, per draw in its own uniform block, so it never perturbs the scene-wide shadow settings or other receivers (large values stay bounded by the fixed shadow filter kernel). In baked mode it maps to the cache blur and resolution instead, so softer shadows are cheaper and unbounded by the kernel.

Implementation

double get softness => _softness;

set softness (double value)

Implementation

set softness(double value) {
  _softness = value;
  _paramsDirty = true;
  // The baked cache maps softness to its resolution, so it must re-bake.
  _bakeDirty = true;
}
