I don’t know if this is the right forum for asking this:
Is there an addon that generates a ‘render report’* and saves it along the rendered image?
*It would be a txt with information along the lines of:
Total render time.
Memory usage, Scene, Render layer, passes
And most importantly: a comment written by the user.
For example: “In this picture of bread, SSS is turned off”
I’ve never heard of such an addon, but you can turn on stamp in the render settings, that will actually print the desired info and some note on the rendered image itself.
