Title: Best way to reproduce real world samples
Post by: subpixelsk on 2017-02-07, 14:28:10
I have some real world samples of fabrics and leather - what is the best way to digitalize it? I tried to scan it but the colors doesn´t match though the lighting uniformity is perfect.

Any ideas? I do not own any studio equipment or whatsoever only a camera :) and printer scanner

Thanks

I am afraid this is not a matter of one-post answer. :)

You could for example start here: https://forum.corona-renderer.com/index.php/topic,10409.msg66470.html#msg66470

Can you post your scans? Maybe I can give you somepointers.

I've had success in the past making some textures from scanned fabrics. It does however take quite a bit of post work while analyzing the real-world sample to make it look right.

here is what I came with - no postproduction yet

I don´t know how to show you original sample however because it is not accurate even on manufacturer´s website

EDIT: Is it incorrect to just look at the real world sample and the scan and try to match the scan in photoshop by eyeballing?

Nothing wrong with that. At the end your final image should look good, clients usually dont care if everything is physically correct. they want an awesome image, thats what counts in the end. Just make sure the that general structure and color of the fabrics are looking good and give it a try. that doesnt mean that you should try to match it almost perfectly but sometimes eyeballing does the job faster and more painlessly ;)

In this case you could just use some leather bump and then eyeball the colour in 3ds max. Unless you do product viz theres really no point in it being more accurate, if it is on furniture it will likely be hard to even see the kind of grain on your leather.

Actually I do product viz so I would like the texture to match as close as possible :) but I guess I will try matching this in Photoshop

Hej johnymrazko,

as seen from your ref. it´s a good leather texture you´re looking for.
I know the pain of scanning textures and matching them to the real world example.
(Even more if you´re under some crazy deadline).

If it´s not some kind of unique style fabric pattern, but leather I would go with this:
https://www.arroway-textures.ch/de/products/designcraft-1

This arroway pack includes even a PS file for every leather to set every color you want.
It comes with ultra high res images and good lower res ones.
(All the other layers are there for sure, like bump, normal, glossy...etc.)

I do never even touch my scanner anymore if it comes to leather, since I own this pack.

Hope it helps!
best regards
Nico

Thanks guys for advice. I have more complicated, not generic samples at hand besides this leather, so I will have to come to some workaround no matter what :)

A client of ours used this:

Maybe a bit expensive but it does a great job.

I can not seem to be able to find prices of this - do you have any information how expensive it is ?

Is it not possible to buy the scanner ?

If you email them and get a quote I'm sure they would be happy to sell you one.

But since the price isn't listed on their website, I presume it costs thousands of dollars/euros.
