Hello everyone,
I made a Mistake on the band part. It was just brightening the light but not adding more bands to it. I changed it to make the bands work better.

Whats I changed is that I’m now Multiplying the number of bands first then ceiling it, then finally dividing to the number of band again. What that does is it intensify the light (Darkening in in darker places and lighting it in lighter places) before it gets Ceiled, and after that it get divided to tone down the brightness of the bands.
If your also using the Sobel edge material, You notice that the Cel-Shade gets wash off a bit to where you didn’t notice them at all. What I did to get around it is that I multiply the clamp with scale parameter just to intensify the band brightness. That way it should not disappear completely.
One more thing, if you were playing the game you notice some unwanted bloom or motion blur. if you have the poss process box and have all of them check off it will still leave the default active. You may want to check on some of them and bring them to 0 just to tell them I don’t want to see it.
This probebly Does not answer the grainy part, nut I’ll talk a look into it.
