Auto generate solid grayscale (brightness decreasing) in Pixel Arithmetic across the layers

[drogago]

Hello,
I propose introducing to "Pixel arithmetic" the possibility of generating solid grayscale (change brightness) for different brightness levels for declared repetition of the layer in the sequence and a step in decreasing/increasing brightness across layers.

To be clear:
Input:

• Layer begin: 0
• Layer end: 4
• Brightness: 255
• Layer end: 6
• Brightness step: -1
• Change every x layer: 2

Output:
Layer no: 0, 1 => brightness: 255
Layer no: 2, 3 => brightness: 254
Layer no: 4 => brightness: 253

The tool could generate the file to test the UV intensity emitted by pixels in a given brightness range.

I can try to implement such stepper in the tool.
Currently this can also be achieved with scripting.

EDIT:
Here my solution, a new single input (Brightness step)

By using a floating step you can achieve exactly what you need, as values are rounded a step of 0.49 will yield in: -0, -0, -1, -1, -2, -2, -3, -3, .....
This is with Subtract 0, +0.49 but you also can use Set brightness with 255, -0.5
