i made that simply by adding rgb till i hit a clamping point, kept
precision before 0 and after the clamping point, and you can subtract
and add it through the clamping point.
I swear this makes photo production easier, anyone heard of this

Very interesting! but I have no idea how this works!
its really cool!
well just say you stopped getting brighter at 0.5. thats the basic
hmmm, but you add rgb values until a clamping point, which comes from
to make this:
here i start with a peach sillouette (pretty poorly drawn)
then every brush stroke, i remove a little red, more green, and even
when i hit say approx 0.7 red i stop adding red, 0.6 green i stop adding
green, 0.5 blue i stop adding blue.
its cool stopping per channel unique so you can get a glow effect around
the ending cell.
the tricky thing is you do it on a floating point texture so you can go
past and back the clamping point. (so the brush works in reverse)
rinse and repeat twice with slightly different settings.
Very clever! I can just imagine what effect it’ll do on real pictures!
have you tried?
im trying im trying, its still in early stages…
ive actually worked a little more, but this came out too deep tanned, im
remedying the situation right now. (im going for photo finish now, but
go easy on my results, still early stages like i said)
(another interesting failure)
i know what im doing wrong, ive actually got another pic thats slightly
better tuned to natural skin, but i havent uploaded it, besides i can do
better just gotta have another go.
It looks very artistic, I mean, looks like a paiting by hand, not from a
What if you use an HDRI?
funny you say HDRI, because im actually using a high precision floating
point texture for the brush strokes themselves, before clamping off. im
happy with this result, ive worked out im too lazy to bother making
something epicly neat and real, this will just give me the basics.
clamping off rgb at different speeds is all you need to do - it is good
enough for sss effects, ok, this is over with.
