FOIL-O-MATIC 3000

you give it a spec map, it gives you the weird pink roughness picture SL wants. made for people who use ms paint, by a webpage that is cosplaying as ms paint.

A dark grey bat pony with big red eyes and a moon and cloud mark, trotting along

step 1: feed me the spec map

drop the PNG here or click me. click me!! CLICK ME!!!! (ctrl+v works too)

right now i'm using example_foil.png, which i made up. it has a fingerprint on it, like yours does. give me a real one and i'll forget this one ever existed

step 2: fiddle with stuff (or don't)

flip it pls (untick if your picture is already a roughness map)

shiny bits. how shiny?

dull bits. how dull? (fingerprint zone)

is it metal?

yep nope some of it

step 3: look at it

your spec map, untouched

The packed roughness texture to upload — the thing SL wants. **it's pink.** it's supposed to be pink. leave the pink alone

the ball. it's my best guess at the shine, SL's lighting will look a bit different. click a colour in the palette at the bottom to paint it

step 4: save it

or right-click the pink square and pick save image as. same file either way

step 5: put it in SL

upload the pink PNG and your diffuse, same as any texture
in your inventory click +, then New Material
Base color gets your diffuse. for foil keep it light and silvery, and colour it wherever you want coloured shine
Metallic-roughness gets the pink one
set Metallic factor and Roughness factor both to 1. the factors get multiplied with your picture, so 1 means it uses your picture exactly as it is
save it, drag it onto your thing, admire foil

facts nobody asked for

roughness is almost upside-down spec. spec is how strong the shine is, roughness is how sharp it is (0 is a mirror, 1 is chalk). flipping is a really good guess, but i'd feel bad leaving out the "almost"
why pink? red is 255 so nothing gets extra shadow, blue is 255 because it's all metal, and green is the roughness. shiny bits have less green, so they go pink. dull bits go white
pick "nope" for metal and blue drops to 0, so it goes red and yellow instead. also correct. also please leave it alone. pick "some of it" and blue copies your metallic map, so foil goes pink and paper goes yellow. a rare foil card ends up looking like a fruit salad. this is fine
on metal the shine colour is the base colour. want gold foil? paint the diffuse gold
roughness is just numbers, so no sRGB stuff happens to it. green 128 means 128 out of 255, which is 0.502 roughness. exactly 0.502. i checked twice
SL textures top out at 2048 x 2048, and the uploader squishes everything to 256, 512, 1024 or 2048. it really likes powers of 2
every time you touch a slider this page looks at every pixel again. a 1024 x 1024 map has 1,048,576 of them. it doesn't mind. it likes it here
ms paint came with windows 1.0 in november 1985, so it's older than SL and probably older than your tinfoil
the palette at the bottom has 28 colours because the windows 98 one had 28. i counted them
