I’ll admit I’m not 100% familiar with the AlphaComposite blend mode, but I first noticed the issue when using it so that’s where I started with the initial post.
Later tests in the material editor showed the same results regardless of the bled mode - textures and gradients appended in the alpha channel always look a bit off, they have their values shifted a bit?
Like in the final image you can see that the green channel from the textures coordinate node is appended in both the greed and alpha channels, but the debug view shows different values for it in both in contrast when the red channel is appended to the red and blue channels it shows the same values. It looks like it might be some compression thing but I haven’t really managed to find any info on it.
Any ideas if this is normal?
Alpha component value, displayed through debug material function, is located lower than green value, and therefore will have higher value of G component of texcoord.
