Shadow flickering in greater distances

Unity Engine
1

Hi,

this is actually my first call for help here … so please be nice:)

I have problem with shadow flickering when my camera is far away from scene center.
I am generating my own terrain (but it also happening on classic models and standard primitives) - as my camera is traveling away from zero(scene origin) - more and more shadow artifacts are visible - see image below.

Image was captured when camera was in distance about 15 km (15000 unity units).

How can I fix it? There is no way to make an open-ish world game? Do I have to move world chunks to zero when player is far away? → that is sick:smile:

I am using Unity 5 on Mac.
Tested with Deffered / Forward settings.
Tested with different materials.
Tested with different shadows and quality settings (resolution, best fit, close fit, various shadow distance etc).
Tested with different near/far clipping planes - this only works when I change near clipping plane to brutal and unusable values.

Thanks for any help and assistance you can provide.

Tom

This can happen too if the camera near clipping plane is too low. Try increasing the camera near clipping plane.

I know…my near clipping plane is 0.3 but if you are far away you must raise it to 3…and if you go more and more away its not enough and you must raise it to 6…and even more further you will raise it again :slight_smile: thats not real solution :frowning:

What solved flickering for me was the Bias and Shadow near plane settings in the Light component.

Same problem in 2019, it is not acceptable.
