Shadows disappear in certain camera angle

Unity Engine
1

Hello.
I’m facing a new problem with Lighting. Shadows are blinking in certain camera angle. I recorded a small video showing this:

I’m using Realtime GI, I set all UV charts for objects, trying to reduce the time to build light. And suddenly this problem started to happen. I haven’t changed anything, and it was working before. I really doesn’t know ho to solve it. I searched a solution, but I still didn’t find any in the internet. Does someone knows how to fix it?

Just for knowing, I already tried to change Shadow Distance on Quality Settings, I’ve changed Bias and Normal Bias and Near plane for Directional Light, I have changed Render mode to Importan and nothing worked for me.

I’m using Post Processing Stack and Deferred rendering mode for the camera. I’m also using Linear Color Space.

Sorry if I missed it (can’t watch the video now) but what rendering pipeline you are using?

I’m using the built-in rendering mode.

Can you try removing the bright white objects on the wall to the left?

What lights are influencing the GI in that scene? Try also just using realtime lights without GI and see if you can still reproduce the issue.

The only light that contribute to GI is the Directional Light.
I removed GI and the problem still persists. I was using Unity 2018.3.14f, then I switched to 2019.2.8f. Now the problem is gone in the new version. Maybe it’s a bug with the engine.

Sounds like a shadows issue. Can you log a bug for this?

@diasrodrigo In the editor use the menu: Help > Report a Bug. In the window that appears, you can describe your problem and upload your project (so that we can reproduce the bug in our end).

Ideally, you would first “slim down” your project to a bare minimum. You can do this for example by removing and disabling as much as possible (while still keep the bug visible) before you submit the bug report.
