Overview ¶
During rendering, Karma saves a variety of statistics about the render process. When the render is completed, the husk
render utility saves the statistics as metadata in the rendered EXR image.
You can extract and view the render statistics for on-going and completed renders using the following features.
Render stats sidebar ¶

The renderstatsreport
