Weathered by time - procedural only - shader available

Post by arc en ciel » Wed Jul 06, 2016 1:02 am

Hello,
here some tests I did using free scanned models from http://threedscans.com/,
it's all isl based, since I can't write ISL from scratch, I hacked all codes from material's database and codes found in the forum.
The idea is to smear, add dirts, damage by water, give appearence to polish non_homogenous manner.
It's basically some multi-coating shaders blended together :mrgreen:

have a super day

EDIT :
a variation tweaking snow/rough shader, I add color's pickers for shades and try differents function in Zangle, I can't get a gradient in x direction by now...

very nice!
for directional control, look at the code of this one:
http://www.indigorenderer.com/materials/materials/1132

or this one:
http://www.indigorenderer.com/materials/materials/1133

"snow cover rough" was the initial experiment and I improved it later :wink:

Tonight when you're sleeping I will sneak into your computer and will steal this material of yours, it's amazing! :D

What about a procedural pigeon dump shader?

awesome material!

the bird poop will eventually be possible etienne : D i guess isl needs a raycast function, to detect silhouettes above the surface points.

hello,
thank's all.
@ FakeShamus : yes, I'll have a look to your mats :D . Some cool formulas for gradients come from sloopy-paint by Fused and dryingSpeed / Thickness system by CTZn... ISL by ONO and Galinette are really inspired too... and all other people :)
and now some images, without postprod, maybe a little too colorful :mrgreen:

hello,

I share with you a simplified version of this shader :wink:
reference image is AEC_LS

ISL in blend channel is used for manage the fusion between Mat A and Mat B
ISL inside color channel or exponent channel manage color, I try a clamp in global output for simulate density.

probably some of you will recognize their codes :lol:

Nice serie, I like the simple stained polished metal fom statuettes_49m_944spp_614ksps.jpg.

You could add a vertically stretched noise to mix angles in order to smear the effect and avoid neatly bordered regions.

the stained polished metal guy on the right ? it's a live-tweak result and I don't save it... it looks like a coat with ISL in Thickness with phong substrate maybe AG or CR...
I try to reproduce it here, but I could not not prevent me to put some ISL in Roughness too, so disable it for have only peaks-and-valleys effect, I named it SC_crevasses_Metal.igm. "Crevasses cursor in Thickness chanel increase or dicrease solarize effect Image
