This is amazing. Back in the 1990's, when I worked in 3D, a resource
like this would have been an immense force multiplier. Back then we had
BBSs to share models, but nothing like this.

on more natural assets. We decided to give it a try, and within just
two weeks, we reached 100 patrons. So, ShareTextures is funded by the
patrons, and as a result of this support, we continue creating.
We have our website because we want to provide some advantages to our
patrons. Additionally, it helps us promote our supporters, partners,

Personally, I appreciate the accessibility and collaborative

community involvement, which I value. For example, if you check
ArtStation's or Unreal Engine's Learning sections, you will see
free tutorials from real experts. This exemplifies the power of
the internet.

Here's their argument (which I disagree with, but I believe

it):
1. Person A starts creating work W and selling it as a

2. Person B also starts creating work W and giving it out
for free (with some Patreon income, but that is not the
point here)
3. Person A can no longer compete with person B, because
free is free. Person A is no longer paid
ugh123 wrote 2 hours 17 min ago:
If someone can create or reproduce the same kind of work
that Person A produces, then that work effort (not the
work product, the work) holds less value. Person A
should do something to add more value.
A similar argument can be had for something that can be
made cheaper than a more expensive option. If my company
makes a widget that takes 100 people to make over the
course of a year, and then someone comes along and finds
a way to make it at substantially less cost (not labor
costs) via technological improvement, then seems like OP
would similarly be against this, which doesn't jive with
nearly any definition of capitalism.

What is PBR? Not Pabst Blue Ribbon! Here's a brief description from
Adobe:
Physically based rendering (PBR), sometimes known as physically based
shading (PBS), is a method of shading and rendering that provides a
more accurate representation of how light interacts with material
properties. Depending on which aspect of the 3D modeling workflow is
being discussed, PBS is usually specific to shading concepts while PBR
refers to rendering and lighting. Both terms describe the process of
representing assets from a physically accurate standpoint.
cubefox wrote 1 day ago:
PBR textures don't include just the usual colored images, but also
other surface properties that influence how specific surfaces
interact with light. Like roughness, glossiness, elevation (surface
normal vectors), whether the surface is a metal, whether it has
specular highlights, whether it appears fuzzy, whether it is partly
translucent (like skin) and so on. The combination of such textures
is called a (PBR) "material".
It's called "physically based" because there exist simple physics
formulas for these properties, so it luckily isn't necessary to
simulate the all microphysical details that cause them in real
objects. Similar to how one can describe a gas with a few parameters
from thermodynamics without considering the molecular details that
explain those phenomena.
In old 3D renders everything looked like plastic because they had
only very primitive surface properties.

When it comes to 3D data, exchanging geometry has been possible for
a long time. Essentially and most of the time we just use triangles
as the lowest common denominator. Most of the difficulties are more
or less accidental complexity because of different formats.
When it comes to textures this was not possible for a long time,
because every renderer used its own algorithm and they all had
different parameters. There was no lowest common denominator.
When Disney invented BSDF it allowed the exchange of realistic
materials for the first time. The "format" won and is what is sold
or given away as "PBR-Textures".j

Don't know of anything like this, but this is a really good idea! It
would be sweet to have a scene and renderer with well-known
properties (which could be adjusted to account for style;
realistic/toon/dynamic lighting/baked lighting, etc) which could be
dropped in to a webpage so that users could mess with it. That way,
developers could independently include it and write their own ways of
injecting the assets.
The end result being a web widget that is a 3D environment with
whatever the developer wants to put in it (with some defaults like
"sunny outside", "sun room", "basement", "cave", etc), and
drag-and-drop asset selection for users to view the showcased assets
in the scene. Could even double as a code-guide, based on your idea
of including functioning TV and Radio assets (an example of how to
include this functionality into the assets). Overall, just a really
great idea!

is problematic across different countries, I believe. Actual public
domain really is âcopyright-freeâ, and it makes sense to describe
CC0 as making things âcopyright-freeâ to a general audience that
may not be familiar with the subtle intricacies of copyright law. It
is true that only the original copyright holder has the authority to
release their works into the public domain, but once theyâve done
that, copyrights are no longer held, and the work is no longer
subject to protection under copyright law. [1]

anticorporate wrote 1 day ago:
Right... CC0 exists because there is no such thing as relinquishing
copyright in many countries, including the United States. It's a
license that allows the work to be used as if copyright were
relinquished. If I create a work and license it under CC0, I still
own the copyright, I've just given everyone a license to use the
work in such a way that I cannot enforce most or all of the rights
associated with my ownership of that copyright.
dahart wrote 1 day ago:
CC0 a license that relinquishes copyrights. Youâre right that
itâs a license and not public domain, but otherwise making a
distinction without a difference. The stated explicit intent, and
the rights granted by the license, are to provide a version of
public domain that is unambiguous and works globally.
Your terminology is a bit funny when you say âI still own the
copyrightâ or âall of these works are copyrightâ. Works
arenât copyright, works are protected by copyrights that
authors have⦠unless the author waives those rights. The
copyright one has by default is the exclusive right to copy and
distribute the work. Once you give that away, either via license
or public domain attribution, itâs irrevocable and permanent,
and thereâs nothing of value in the idea that youâre still
the copyright holder, since there are no longer any copy rights
retained nor copyright protection under any laws.
In short, itâs perfectly fine to call CC0 attributed works
âcopyright-freeâ because thatâs what the license actually
does, it âwaivesâ all copyrights and ârelated rightsâ,
and allows the public to copy at will, forever.
BTW I donât think itâs true to say that thereâs no such
thing as relinquishing copy rights in many countries, thatâs
too strong of a claim. It is true to say thereâs no such thing
as public domain, but copy rights (or ârelated rightsâ) can
be transferred and/or waived pretty much everywhere.

And their point is that saying âcopyright freeâ will probably
be more immediately understandable to people who donât know

By saying copyright free, more people who need freely-licensed
works like this are likely to use it instead of being warded off
by âthis does has a license, itâs copyrighted, but itâs
actually free because of the licenseâ
Colloquially, itâs the same thing.

I've had my eye on this for a couple of months now because you guys are
doing exactly what I'm doing when it comes to modular asset/utility
development: putting it in the public domain, where it belongs.
I'm all for making money on specialization or convenience, but I really
can't find it in myself to build a perfectly useful something and then
only use it for myself unless someone else can pay for it. As long as
it's fully modular, I just have to give it away for free. Some things -
no matter how much work they took to make - are just not worth paying
for. Or, at the very least, I would never pay for them. So rather than
just keep everything to myself so I can use it the one time, I can't
see any reason not to just make it entirely available to the public.
And, good god, I would be so embarrassed to see my name in the credits
of something with a label like "provided image formatter", or
something. So attribution is something that I really couldn't care less
about. It's always a nice gesture, but some things just aren't worth
attributing.
All of which is to say: I love your interest in releasing these things
to the public domain, and I'm very eager to join you! I've worked in
games since before the original THQ went under, and have been using
Unreal for the last 6 years or so. I'd be happy to get into whatever
process you guys are using, and provide assets to whatever
specifications you enforce. I find the most important thing about
assets is that they be uniform (so large-scale changes can all happen
in the same way, per asset). So I'm happy to conform, just so I can
make assets that will act well in-editor.
Unfortunately, I'm mired in some side-project dev work, and won't be
able to work on games, or game assets, probably for the rest of the
year. So I've got to put off helping until I can clear my plate some.
But I have bookmarked you guys, and will follow up to see if you have
any interest in additional help with this kind of work, as soon as I
can!
Aside from all that, thanks again for providing this. It really is a
useful and altruistic endeavor!

IF you want to make it high-quality, there is a technic called
photogrammetry. You need to take hundreds of photos under same
light, without shadow or reflection. Then you create the 3D model
of the facade using photogrammetry software like metashape or
realitycapture. After you have the 3D model, you need to transfer
3D data to 2D texture. It's called baking. After baking is done
you endup with basecolor(diffuse/color), height(displacement),
normal and ao(ambient occlusion) maps.
If you are looking for a basic way, just take one clean
photo(without visible shadows or reflections) There is method
called Bitmap to material. Basically, you grayscale your image
and using that grayscale data to create other maps like bump,
roughness height etc. If you've experience in that area you can
make them in Photoshop. Adobe Substance Sample(Substance
Alchemist) has great abilities to generate using that method +
AI.
To clear reflections you need circular polarization filters. You
can also use cross-polarization method to clear all unwanted
reflections. But It require addinational light source and linear
polarization filter.
