Shadow glitches when importing blender model

Hi,

I’m getting weird shadow glitches when I import a simple blender model into Unity. I tried tinkering with the lighting settings and found that it only occurs when I enable realtime shadows (which is what I want). It also only happens when using a blender model - when I created a simple cube in Unity the issue does not occur.
I’m using Blender 2.82, Unity 2019.3.5f Personal and Ubuntu 18.04.

My project is in fact open source so you can actually easily check it out for yourself if you like: Robert Bleyl / Drone Control · GitLab

Here an example of what the issue looks like:

Feel free to ask more details if necessary :slight_smile:

I don’t know if this has anything to do with it, but because it looks a like a plane is intersecting the object where the shadow problem starts to occur, there is this Shadow Near Plane Offset setting. see: Unity - Manual: Shadow troubleshooting
