I followed a tutorial on how to make cel shading and it works great, but there’s an area that i want the dark area to be 0, but i don’t know how can i change the value outside the shader blueprint
Hi @chromer.exe,
If you mean to say that these values are good for you, but you have a specific area on your map where you want to change the cel shading, then you’ll want to use a localized postprocess volume.
Go ahead and make a duplicate of this material with the new dark value you want. Then, create a new postprocess volume and add that material to it. Instead of checking “Infinite Extent” like normal, instead scale the bounds around the area where you want this effect to take place.
Then, inside the new postprocess volume, you can set a blend radius for a smooth transition into this new effect. You can also set the priority here to make sure it always gets rendered over the existing postprocess.
Good luck! Let me know if you have any other questions.
