Title: Suede / Nubuck Required
Post by: volcomjon on December 02, 2018, 02:58:36 AM
Hi All - looking for some help in creating a suede / nubuck texture for footwear (like the photo attached).
ive had a trawl of google, and found some alacantra texture, but its not quite suede.  I also found a test shoes post where someone had created a suede look, but didnt give details to all the settings.

could someone assist me in creating this, where to start, what settings etc.
it looks like velvet as a start material, then adding bump map to it - but cant really get correct effect.

many thanks
(using KS 8.1 pro)

This is a difficult topic. At least, it was for me when I was working on suede leather bands for wrist watches. A single Bump didn't work well, because there is more imperfection in the material - the fibers change their direction too. You can meme that by changing the color value/saturation with a noise texture. It works for total shots, but don't look good on close-ups and macro shots. On my project I ended up using particles in Blender. With all that I still failed and lost the client :)

But if I would need to do it again, I would contact all those people...

... and ask them for an advice. :)

P.S.: I worked in KS7 then, maybe the new KS8 Displacement feature can help.

Thanks for the reply!  hmmm, glad its not as simple as click click done, otherwise I would have felt a bit stupid.

I'll tap up those artists and see if they can offer some advice, however I can see that none of those renderings used keyshot as software, so no doubt they used very different techniques.

thanks again

I would guess that you can start with a velvet material and use the bump add utility to combine very small and slightly larger noise bumpmaps. Make the bumps really tall (at least over 1, but maybe more towards 3) to force that grainy look.. You can loop the output of that into another bump add if you need.
Not sure how much displacement will help you, as the details are tiny and you'd end up with a massively dense mesh..

edit: I would probably use that combined with an actual texture for at leat the diffuse map.. something like this (not free): https://www.123rf.com/photo_53005955_beige-suede-soft-leather-as-texture-background-old-leather-brown-chamois-texture-fluffy-and-soft-sha.html (https://www.123rf.com/photo_53005955_beige-suede-soft-leather-as-texture-background-old-leather-brown-chamois-texture-fluffy-and-soft-sha.html)

Definitely a tricky material due to the features that camomiles describes.

Depending on your needs, perhaps the two suede materials from poliigon.com will help you out: https://www.poliigon.com/search?category=suede

I believe that a well designed/placed displacement map can be a big helper -  especially on the edges. With a regular bump the edges will just look flat. The ,,tousled" look will be lost without any variation.
Particles add an additional level of realism on close ups. But it depends on the final project target and the model.

Yet, the Suede material this guy :

ok - had a play, here is the result.  what do you think?

At the further away distance, the texture looks ok, but close up the bump is too harsh (see second attachment) - so may have to dial it down a touch for close up shots, also, the bump I have appears to have "threads" in it close up, so again, probably need to adjust that to a more uniform noise texture.

advice?

the distant image looks pretty good in my opinion, but you are right, the close up does not look like Suede.
it looks more like a fuzzy fabric, that is worn out in some areas.
I do not think, you can control that with your parameters, I assume that the image you use (for specular and bump?) is not the right one.
however, to give a distinct feedback, I would need to see the images !
I might be wrong ...
cheers

Here is an attempt using primarily procedural Camouflage and Spots textures as displacement, with a bit of normal/bump mapping.

Cheers,
Eric
