When I try to render close-ups of objects as small as a few cm in Eevee, I cannot get the shadows to work properly. With Cycles, everything is fine, and I can accept the difference in look between both render engines, with the exception of the missing shadows.
Here is a comparison between both engines with the same scene:
The disk-like object is about 1.5cm in diameter. The scene is illuminated by a spot light and low level world background with a solid color.
How do I set up the shadows ideally for small scenes? Which parameters are most important when it comes to scaling, and what is their influence? Is it possible to even have shadows in Eevee in that scale?
I have read the Blender Manual - Light Settings-page but did not find a suitable set of settings with it.
