>>2796796As a generic mirror effect, this would work with mirror parent shaders like the one by Bandages on DA that uses an alpha mask and changes its reflection based on angle (fresnel math). But any transparent reflection will look better with proper gamma, by outputting as linear with the 'SRGBWriteEnable = 1' pass option. This will stay linear if output is redirected to a float texture by a post-shader, but will convert (after alpha blending with the target) from float linear to 8-bit sRGB if output is to an 8-bit texture.
So it works great until you use a post-effect which doesn't know that it's getting a linear-light input.
