Hello Thiago,

Sorry for the delay.

What lighting, appart from the neon, are you using ?

HDRI, Sun ?

Which rendering parameters did you use for this image ?

Could you attach the atla of the file you used to render this image.

In you render, I think most of the grain can be removed by increasing the global illumination interpolation value to 5.

I tried to build a scene looking like yours.
I have a night heliodon, one suspended lamp and a lamp object with one face set with neon shader.
I used the "Low light" "medium" pre-defined rendering setting with AA 3x3 to get this image:

In your image, it seems your camera is outside in day time.
did you check the "enhanced background" ?
what is the lumen value of your neon shader ?

I think you need to increase the interpolation to 5 and you do not need the AA set to 4x4, 3x3 is enough.

In fact, you should try using the "Low light"+"medium"or "high" parameter pre-set, it should look better !
