How to set a layer's material to 0?

[human890209]

Hi,
I write a script which copys layers at the same PostionZ. How to set the layer's material consumption to 0ml of those copied layers?
Layer's MaterialMilliliters property can't be SET by script.

You can't. That property is auto calculated.
Why you want to set to 0?

Thats what dim wall is for with Elephant foot calibration on UVtools

By the way, the current UVTools' erode fix for elephant foot is good, the double exposure trick doesn't work well for bottom layers, I apply it only for Normal layers. A bottom layer takes ExposureTime+extra time with one single erode layer.

Any dim pixel loses detail. The UV light blurs. I only apply dim pixels for infills, I never dim a wall pixel.

Depends on printer and light source.
At some point a dim percentage will match a full white at n exposure time, it's not linear but if linear 255 at 2s would be the same as 128 at 4s

Yes, I tested my QIDI 6.08 Mono screen.
I use Exposure Time Finder with Pixel Dimming to find the exposure time of several dim values, 255, 191, 159, 127. The exposure time is not linear and all dimed ones lose 1~2px details. I guess the results are caused by the light scattering of a dimed pixel.
