====== Path tracer ======

PT is a ray tracing method, with the help of which a global illumination simulation can be carried out. Rendering with the Pathtracer option is qualitatively better compared to the standard ray tracer.

The images generated here support diffuse reflections very well, but can be noisy. Its options are located in the grey zone with no grouping label near the bottom of the Twilight renderer settings.
<del>be noisy. The top field Pathtracing options contains the
Number of paths property. This property is only evaluated if the
Pathtracer MT has been selected as the ray tracing algorithm, and has a strong effect
on the noise in the rendered image. The higher the value, the less
noise the image contains, but the longer the calculation will take. The
initial value of 25 is considered a good compromise.</del>
The Recursion depth property determines how often light in the scene is
scene is reflected back and forth during the calculation. The value 0
would mean that all reflections and refractions are excluded. To obtain realistic
images, it should be set to 6.
<del>The Priority can be used to determine the resource consumption
during the calculation can be determined. The high priority option
option, all available resources are used for the calculation. The option
medium priority option offers the option of loading the operating system
to a limited extent. With the low priority option, the calculation is
regularly paused, allowing work in the operating system in parallel with the
calculation is possible.</del>
In the <key>Antialiasing</key> method drop-down list, the user can select whether the image is to be is smoothed using super-sampling or whether no antialiasing is performed.
The number of sampling passes can be controlled via the <key>Grid size of super sampling</key> field. It should be noted that the square of the input value will be used by the algorithm.
