It might be a nice feature to be able to save, and perhaps be able to control sizing, of the Preview render?
Besides print screening:
The preview is indented mostly for reviewing light setup before more time consuming bake. The preview doesn’t, for example, include reflections, or sky textures. In the editor you can capture screenshots of baked scenes with P button, and it allows to control resolution.
Thanks for the clarification, Jan. Useful to know, thank you.
