| Statistics | Description |
|---|---|
| Total number of traced rays | This is the count of all the rays traced during a render. The following sub-categories simply specify the count per ray type. The special waste sub-category counts the rays that have been traced but could have been avoided - this is related to the internal workings of the render engine and is not user controllable. |
| Total number of shader calls | Total count of shader calls. Sub-categories show the shader calls per ray type. |

distribution_of_ray_types | table | A table describing how many rays were traced, per type (specular, diffuse, transmission, ...). Note that this is a table, not an histogram. | |||||
