Question

I started a new project and all the self-shadows look like in the image below.

How can I fix this?

Answer 1

Based on the direction of your shadows. I think you are using a directional light. If you want your scene to be equally lit or dim with some factor. Ambient Light is the type of light you have to use along with your current Directional or other types of light in your scene. By balancing out between Ambient Light intensity and your scene lights you can get the results you are aiming for.
