The Render Tools aim to streamline rendering in Blender, with a focus on creating many iterative variations and explorations, that can be revisited at a later time.
For the following three main tools, modifier keys can be used to adjust render quality and resolution on the fly, thereby avoiding having to manually adjust any render settings.
Check out the tool tips.
Render the currently active camera and save the image relative to the blend file.
Render the currently active camera
$seedcount times, combine them to remove fireflies, and save the images relative to the blend file.
Final (Seed) Render
Render the currently active camera + a cryptomatte, save both as
.exr relative to the blend file, and setup the compositor.
