Is there a way to change the default for saving a render to RGB instead of RGBA? This saves me disk space when working with renders that don't have an alpha-channel anyways.

I can't find anything on it under Edit > Preferences

Render Screen


You need to save your preferences as a startup blend-file.

  • Create new default blend-file
  • Change the image format settings in Output Properties > Output
  • Save the blend-file
  • State the blend-file as the default startup blend-file Info Editor > File> Defaults > Save Startup File

Make sure you're in the saved blend-file when you state the blend as the startup default!

Note: I'm not sure if this overwrites previously saved blend-file defaults.

Unfortunately I think not. But it should for all future saved blends.
