It is working properly, it's just not working the way you expect it to :) There might be some special effects where you want to be able to control it, so I'll leave it open!

Also, transparency is tricky, there's no perfect solution. The issue is that a pixel either writes to the Z buffer, or it doesn't. There's no "softly" writing to it. This is why alpha clip is always sorted properly.

Are you using deferred or forward rendering?

Levels in photoshop doesn't have much to do with saturate/clamp0-1 :)

Levels in photoshop lets you alter the distribution of bright and dark colors, both in its input and in its output, so you have control over the contrast and brightness of your image.

Saturate/Clamp 0-1 makes all colors below 0 outputs 0, and any values above 1 outputs 1.

If you're talking about the saturate() function in shader code, or the saturate node in Strumpy Shader Editor, then the node you're looking for is "Clamp 0-1".

There's no color "saturation" node yet, but you might actually be able to use the desaturation node and use a negative value.
