For example if the Max number is set to 10 there will be no more than 10 diffuse rays, 10 glossy rays and so on. The Transparent rays are controlled separately. These values can be adjusted to limit the number of any kind of ray, be it diffuse, glossy or transmission. I will go through all of them separately. These values all control the behavior of the light rays in the scene. This is the default settings for direct lighting preset: The "Light paths" rollout control the number of bounces for certain types of rays. Rays are rays that travel within materials that can transmit light (glass, translucent materials), and finally Shadow rays are called rays that examine areas that are blocked from a light source by Reflection rays are those that hit the Material's surface and travel on.
The shaders of a Material determine which rays would bounce off of the surface and the manner.Ĭamera rays are those between the Object with the Material and the Camera. These rays are very closely connected to the type of material surface (or material's shaders). The theoretical grid behind the engine is visualized here. I suppose learning what this setting does not only helps understanding the path tracing algorithm in general,īut can also greatly reduce the rendering times once wisely used.įirst some theory. It was the "Light paths" Rollout in the "Rendering tab" that I was going to examine this time. This should serve (again)as a manual (or part of the manual) for decision making during setting up of cycles render. The documentation is not covering everything or at least not in the scale any user would ideally prefer. Now, together with the blender's node system it is even more powerful CG tool! (I love you guys). It has been neatly implemented into the Blender. It has been around for some time now and it is a great FREE option for an unbiased This time I decided to examine 'CYCLES' which I have grown very fond of lately.
In the past I have written a similar tutorialĬovering some settings in the great YAFARAY raytracer.
Once again I immersed myself into the wild waters of rendering engine.
