WebWhen Linear color space is used, render textures can perform Linear to sRGB conversions when rendering into them and sRGB to Linear conversions when sampling … WebThe gamma correction is used to compensate for both. The transformation is just "linear value V to some power Gamma", i.e. y(v) = v^gamma. Colorspace transformations involve the complete chain from input values to whats sent to the display, so this includes the gamma correction. This also implies that you should not manipulate the gamma ramp ... WebIn Gamma, it appears normal, but in Linear (the space we are using) it appears very dark.
