Point light’s shadow peter panning

I noticed that point light’s shadow has less peter panning the further away it is from the end of the light’s range.
That means that if I have shadow casting point lights with huge range, I can avoid peter panning, but that’ really expensive since they won’t be culled(?).

100m range, light slipping under the door:

800×600

800×600

Is there a way to avoid peter panning without huge light range?

try
light.shadowBias = BiasParameters(0.0002f, 0.5f);
light.shadowCascade = CascadeParameters(10.0f, 50.0f, 100.0f, 0.0f, 0.8f);

ShadowBias is for self shadowing.
shadowCascade is for directional light, I’m using point light.

it is offset of shadow

Ok but I’m already using those values since they’re the defaults:

static const float DEFAULT_CONSTANTBIAS = 0.0002f;
static const float DEFAULT_SLOPESCALEDBIAS = 0.5f;

set bias to (0, 0.5), this can cause artifacts, but can solve problem

Why is it more accurate with bigger range?

Maybe when you move the light source parallel to the floor the angle of the shadow to the object is changed
