Cycles is using Path-tracing-Tile instead of Sample
https://blender.stackexchange.com/questions/141275/cycles-is-using-path-tracing-tile-instead-of-sample
You are confusing terms. The number of samples is not the number of tiles being rendered.. 8 samples will give you a very noisy image. Read: How to avoid noisy renders in Cycles? What you see as orange squares are tiles being rendered. By default blender doesn't render the whole image, but it splits it in tiles to maximize the resources on your computer.
Path tracing - Wikipedia
https://en.wikipedia.org/wiki/Path_tracing
Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object. This illuminance is then reduced by a surface reflectance function to determine how …

The Sampling panel shows this total number of samples. To visualize how this works, the Progressive integrator simulates one path (or ray) per sample: 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 …
Sampling — Blender Manual
https://docs.blender.org/manual/en/latest/render/cycles/render_settings/sampling.html
Panel. Render ‣ Sampling. The integrator is the rendering algorithm used to compute the lighting. Cycles currently supports a path tracing integrator with direct light sampling. It works well for various lighting setups, but is not as suitable for caustics and some other complex lighting situations. Rays are traced from the camera into the scene, bouncing around until they find a …

Path Tracing • Pure path tracing is the most naïve solution to global illumination – Also the most elegant (my opinion) • Path tracing for Lambertian shading 1.Cast a ray from the camera 2.Multiply attenuation by material • From that point, cast exactly 1 ray in a random direction 3.Repeat step 2 until light source is hit

When we use branched path tracing, we have two additional advanced settings. These are sample all direct light and sample all indirect light . Just like we can give different material properties or features different amounts of samples with branch path tracing, we can give different lights different amounts of samples when these are turned on.

What Cycles Does. Classic path tracing will only follow a single light path, much like a photon would. At each vertex you pick one BSDF/BSSRDF and one direction to continue the path in. Path tracing with next event estimation (as Cycles uses) connects every vertex on the path to one randomly sampled position on a light as well.
Path tracing samples taking long time : blender

Path tracing samples taking long time. Close. 0. Posted by 11 months ago. Archived. Path tracing samples taking long time. I just got into blender and when I have the cycles for the retendering I am using 32 samples and they are taking a LONG time to load all of them. I have a rtx 3090 and can do the BMW render in 21 seconds.
