Shadow Banding

[SpiderPig]

I've noticed a lot of thin banding in the shadows in 0.9.5.  I think it's been raised already but I didn't see an official report.

This is in the default startup map.

I complained about this many times in our Workshops but yeah this looks disgusting. 

What's your lighting setting with this by the way?

[SpiderPig]

I'm not sure on the exact setting, but it's a fresh project loading the default start map.

[SpiderPig]

It's not really the shadows either, it's the lighting itself I think.

[Josh]

That is some very strong banding that does not look like shadow maps.

[SpiderPig]

Yeah it looks like the lighting routine.  Are you seeing the same thing on your machine or is it specific to mine and reepblues?

[Josh]

I do not see this on my AMD 6600, but it does seem sort of familiar...

I have the same problem when I make a point light. X = 2 , Y = 10

 

I'm not sure, but the artifacts disappear for me when I set the min(X) to 0.

Two meters is a very high near range. It should be way less than that.

@SpiderPig In the attached map, I disabled shadows on the spotlight. Do you see the same banding pattern in this map? Does it occur in the editor or only in the game?

[SpiderPig]

No banding in that map.  Not in the editor or in game.  I re-enabled shadows on that spotlight and there's banding in editor and game.

[Josh]

Okay, it must just be standard shadow acne then. The default setting needs adjustment.

I just wanted to put it here.

I think this is fixed on current build of beta branch, please sync to get the shader update.
