Like one in Photoshop color settings.    I can't export areas of a texture supposed to have specific gray values in -game  shader  is needed  without some exte noise.      It's too tiresome to fix it in Photoshop .      If anyone knows a workaround  please share.   I tried to posterize the result in 255 steps before converting  to 8 bits.   Looks ok  in 2d view   but again  noise after export.

it's not enough  actually . if you just convert to 8 bit  by any node it's where substance does dithering too.

But I made a workaround if somebody interested .

it puts white pixel in UV zero  , clamps image to 0-1  then makes   it perfecttly 255 shades of gray , then replace that zero pixel back to original one.  RGBAmerge after it should be forced to 8 bit

A workaround is to force the last node in before the output to 8 bit.
Though I agree this should just be an option you can toggle in the export window.
