The problem is as in the pictures. When Rendered mode is on, light passes through the edges of the model. When exporting to Unity3D, the problem is the same.

Select your light, and in the light properties panel, tick the "contact shadows" box.

  • $\begingroup$ Hmm. Not sure then. Maybe try giving your plane some thickness? It's kind of hard to tell anything else from the photo. $\endgroup$ Commented Jun 9, 2020 at 17:03

  • $\begingroup$ First off, your light type is sun, of which 1000 is WAY too high a value. 10-15 is considered (almost too) strong for a sun light, and most people don't go over 5. I suggest changing it's type to a point light and setting the brightness to 2000 or something... or move it closer. However, If you want a light with good shadows coming (seemingly uniformly) from one direction, I would use a large area light instead of a sun. Looks more natural I think. $\endgroup$ Commented Jun 9, 2020 at 19:13
  • $\begingroup$ Also, you should up the distance of your contact shadows to something like 2M, and in your render properties tab, under shadows, make sure both "high bitdepth" and "soft shadows" are checked. It's not PERFECT, but it makes it a whole lot better. $\endgroup$ Commented Jun 9, 2020 at 19:14
