WebApr 6, 2024 · Godot seems to assume all PNG textures are linear, regardless of any gamma or sRGB info embedded in the PNG. I tested this by hex-editing a PNG to have various types of gAMA and sRGB chunks. This is at odds with most image editors, which tend to default to nonlinear color spaces. So if you create a PNG in e.g. Gimp and stick it … WebExample 24-1. Manually Converting Color Values to a Linear Space. Texture lookups can apply inverse gamma correction so that the rest of your shader is working with linear values. However, using an sRGB texture is faster, allows proper linear texture filtering (GeForce 8 and later), and requires no extra shader code. to what division did zachariah belong
