I’ve recently switched from Unity 4.xx to Unity 5.0, therefore I had to update my project as well and everything works fine except for the shadows. It used to look okay even if it was turned on Hard Shadows with medium resolution, but now even Soft Shadows look terrible! I tryed switching shaders, none of them seemed to solve the issue, which is: The shadows are “shaking”.
Is it some kind of bug which only happened in my project or do you other people encounter it too ?
Did I do anything wrong ? Is it just the new realtime shadows which look awful ?
Here’s a video of it, to see for yourselves: https://youtu.be/LiIA55ay4ro
EDIT: I made some research and last year Unity had problems with Intel graphic cards. I’m Developing on my 2012 MacBook Pro, with Intel HD 4000. Could that be the problem ?
I have Unity Pro and on my old computer shadows do not work at all. On my new computer, shadows work perfectly, EXCEPT, when I have a huge scene. Once my Frame Rate decreases to a certain amount, the processor matter much more than the quality settings. This causes the shadows to glitch out, and even disappear. This problem can be solved by optimizing the scene by decreasing draw calls, combining meshes, and deleting unnecessary assets. Maybe your terrain is too big. This would definitely explain why it works in your new scene. Unity 5 may also have something too do with it due to its advanced rendering capabilities, which requires a better graphics card and processor. If this is a Unity Bug, just rebuild the scene part by part in a new scene; if all of a sudden shadows stop rendering, it is probably due to the last change you have made, if the shadows start glitching out, you need to start optimizing your game, if everything goes well then it was just a Bug.
