Unity 5 Directional Light Shadow Flicker

Question

Hello, after I updated my project to Unity 5 all of the shadows starting to flicker. In Unity 4.6 was no flicker with the setup.

Maybe is this a known bug?

Changing the near clipping distance of my cameras from .01 to .1 fixed the flickering for me.

[Fixed] I came across this issue as well today I am posting because I actually found the answer to shadows flickering and what not with out the help of the forums.

After trying every setting I narrowed it down to the cascade distances of the shadows. After adjusting the "cascade splits" and "total cascades" I was able to remove this flicker effect completely. They are set to a default setting and depending on the camera ditance to your world you will want to adjust these to fit your needs. I hope this helps someone.

Thanks @bellatesla, I was able to find a workaround for this bizzare issue in forward rendering mode. The issue goes away in deferred, but some of my assets aren't compatible yet so this was helpful.

Hm. It turns out that this actually only helped mask the issue. The flickering was present in deferred as well, just not as visibly. It turns out that one of my assets automatically added a special global fog image effect to the main camera which made AA apply ahead of it. I adjusted the order so that AA was last in line and the issue disappeared entirely .

Oh, Thank You very much, bro! I've been struggling with this for days... I've tried everything, literally everything. And only your solution worked. Changing $$anonymous$$ain Camera Rendering Path to "Deferred" solved my issue completely. God Bless You! Cheers!

I had this problem after adding a huge plane in the scene (water). So turn receive and cast shadows off on the plane or huge object. Worked for me

I had a weird gradient appearing in the shadows and turned out to be a massive floor bouncing light all over the place. Removed shadow from floor and added fake small floor to pick up the shadow and now works fine so HUGE thanks to @karpae2k for suggesting this

We're having the same issue. Moving the znear from 0.1 to 1 improves the flickering, but is not an acceptable solution for our project.

Same issue here. Deferred, linear, HDR (and I made sure of it).
