Paper Texture: 0.0.80 → 0.0.81

0.0.800.0.81notemigration
colorFrontcolorShadowtaken directly
colorBackcolorBacknow hidden behind additional colorPaper layertaken directly
—colorPaperkinda what colorBack wasusing mix of colorBack and colorFront: mix(colorBack, colorFront, 0.2 x (1 - sqrt(contrast)))
contrast—it was used for pattern strength, for image blending, for a way colorBack and colorFront are mixing intaken as sqrt(contrast), feeds blending, roughness, wrinkles, crumples, drops and colorPaper
fade—removed, no replacement; muted the pattern via a noisy masktaken as (1 - 0.25 x fade), mutes roughness, wrinkles, crumples and drops (uniformly across the canvas, up to 25%)
imageimage
—blendingnew (contrast used to do this)taken as sqrt(contrast)
—distortionnew (the image was always distorted)set to 0.7
—clipnewset to false
—anglenewset to 300
seedseedsame prop, rebuilttaken directly, although old seeds cannot be matched visually
roughnessroughnesssame prop, rebuilttaken as 1.5 x roughness x sqrt(contrast) x (1 - 0.25 x fade)
—roughnessSizenewtaken as 0.65
—roughnessRowsnew0
fiberfibersame prop, rebuilttaken as 1.5 x fiber
fiberSizefiberSizetaken as pow(fiberSize, 0.2) x 1.2, aiming to get visually close to the update scaling
—foldsname reused: old folds are now crumples, new folds are straight lines we never had0
—foldSizeXnew0.6
—foldSizeYnew0.44
—foldOffsetXnew0
—foldOffsetYnew0
crumpleswrinklesdifferent pattern, close enough to port directlytaken as min(1, 2 x crumples x sqrt(contrast) - 0.25 x fade)
crumpleSizewrinkleSizetaken as (10 - 8 / (9 x crumpleSize)) / 9
foldscrumplesrenamed (different shape and different randomizer, same principle)taken as 2 x folds x sqrt(contrast) x (1 - 0.25 x fade)
foldCountcrumpleCountsame range, 15 max
dropsdropssame drops, different randomizer and color usagetaken as 1.5 x drops x sqrt(contrast) x (1 - 0.25 x fade)
