Title: FOW - Flickering in Linear color space
Post by: GrimmGames on May 30, 2014, 11:28:58 PM

Hi Aren,

I switched the unity color space to linear, and now the FOW asset flickers during startup and during reveals.

Yeah, that's to be expected. Linear lighting has a curve on color intensity. Gamma lighting is linear, but linear lighting is curved (as misleading as it sounds).

You can't blend between fading-out textures that aren't using linear values (read: gamma lighting).

As far as I'm aware, Unity didn't provide any way of bypassing linear lighting sampling on textures created at run-time. Only via texture import settings.

My good friend Lea Hayes just pointed out that there is an additional bool in the Texture2D constructor for linear color space, just after the mipmap bool:

Texture2D(int width, int height, TextureFormat format, bool mipmap, bool linear);

Setting this to true enables the FOW system to work properly in linear color space.

Cheers!

Ah, good to know, thanks.
