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?

The fix for me was setting the rotation on my directional light to have integral values for each axis.

This sounds interesting, integral values, first time I have heard of them in maths or just forgotten. What was your reasoning behind this and how do you implement that? Cheers.

I suspect kideternal meant "integer" or whole, positive number (e.g., 100 vs. 99.9).

Yes, integer. Turns out I'm mistaken about this. All it did was revert to regular realtime lighting, which is nearly indistinguishable from baked in my complex scene until you compare framerate. (I'd have noticed sooner, but my bakes keep locking-up Unity at the end.) $$anonymous$$y apologies. :(

I was able to fix this by unchecking "Cast Shadows" under terrain settings. I really hope they fix this.

Problem is worse in the Editor view than the Game view. I have not actually built the project to see if this problem persist after building.

Maybe something within the Quality settings (Edit > Project Settings quality) in the "Other" section you find the "Blend Weights" option. It tells the max number of bones which can influence one vertex.

I found my own solution, changed the near clipping plane form o.1 to 0.5

Hope this helps

I also found it to be the camera near clip plane to be too low which caused it.
