Strange square-like shadows appear in the editor on Unity 5



- Import the attached project (from - Unity 4.6 compatible)
- Open 0 - Main Scene and press Play
- Select New Game from the menu
- Notice the black squares that show up in front of the main character

This appears to be a regression from Unity 4.6. For comparison, here is how the level looks in 4.6: and here is how it appears in 5.0:

    For anyone else experiencing a glitch like this, try turning off any blob shadow projectors you may have in your scene. Had me infuriated for days before I found it.

    Actually, after further investigation, the problem is a side effect of having more lights than your Quality setting of "Pixel Light Count". While the result might be what you expect from a rendering tech standpoint, it is horrible in actual use when used with terrain. It only affects forward rendered objects, like terrain in deferred.

    To repro, just take a piece of terrain, set Pixel Light Count to 1 and add 3 or 4 lights and slide them around the terrain. The terrain snaps to certain lights and results in nasty sharp edges on the lighting in the terrain.

    This is a huge problem for us. The above bug doesn't mention terrain but this happens to us only with terrain.
