How is sampling similar to path tracing in Blender?
It is similar to Path Tracing, but at the first hit it will split the path for different surface components and will take all lights into account for shading instead of just one. This makes each sample slower, but will reduce noise, especially in scenes dominated by direct or one-bounce lighting.
Which is the best description of a path tracing integrator?
The Path Tracing integrator is a pure path tracer; at each hit it will bounce light in one direction and pick one light to receive lighting from. This makes each individual sample faster to compute, but will typically require more samples to clean up the noise.
What is non progressive path tracing integrator for Blender?
The non-progressive Branched Path Tracing integrator offers finer control over sampling. It is similar to Path Tracing, but at the first hit it will split the path for different surface components and will take all lights into account for shading instead of just one.
What happens to AA samples when branched path tracing is used?
As more samples are taken, the solution becomes less noisy and more accurate. When using Branched Path Tracing, this changes the AA Samples which are multiplied by the Subsamples and improve Anti-Aliasing. Number of samples for viewport rendering.
What is the number of samples for viewport rendering?
Number of samples for viewport rendering. Setting this value to zero enables indefinite sampling of the viewport. The subpanel is only shown when using Branched Path Tracing. Number of diffuse bounce samples to take for each AA sample. Number of glossy bounce samples to take for each AA sample.
How many samples are in a path tracing integrator?
To get the same number of diffuse samples as in the path tracing integrator, note that e.g. 250 path tracing samples = 10 AA Samples × 25 diffuse samples. The Sampling panel shows this total number of samples.
What is minimum number of transparent bounces in Blender?
Minimum number of transparent bounces. Setting this higher reduces noise in the first bounces, but can also be less efficient for more complex geometry like hair and volumes. Probabilistically terminates light samples when the light contribution is below this threshold (more noise but faster rendering).
Why do we use branched path integrator in cycles?
The Branched path integrator splits the ray, sampling multiple directions as well as multiple components of the material (e.g. glossy, diffuse, etc) in one sample: This is helpful because it takes into account light from multiple directions as opposed to only one, as well as giving more control over how different shaders are sampled.
