I don't have much of a complaint about that shader specifically but more about shaders in general. Not even a complaint really. I'd like more variation in shaders, I see a lot of black/white/greys, orange/blue/white, purple/pink, A lot of the shaders use the same base colours and end up looking relatively the same. I'd like if we could make our own shaders (this is obviously wishful thinking and will never happen lol that's fine though). Like you can collect materials everywhere and each one or combination creates specific colours, then you could use the colours you created and shade and highlight specific parts on your guardian. Everyone could personalize, and everyone would look unique (colour wise anyways lol).
