Cosine Spread
Sample spread of rays when using cosine distribution. A value of 1.0 gives a perfect Lambertian distribution.Carousel Image Slider
Bias
The bias will affect the falloff of the curvature and will be linear, decreasing with the distance from the shaded point. Bias can be used to take further samples into account more or less while nearby points have more weight.
- The closer to 0.0, only points closest to the shading point will contribute.
- With the default of 0.5 any points close to Max Distance will contribute less, and points close to the shaded point will contribute more.
- The closer to 1.0, the more all sampled points will contribute. At exactly 1.0 sampled points at all distances will contribute equally.
