From this point to several lessons forward, we will be discussing PBR textures for this lesson video.
We will discuss what PBR is and where to get PBR Texture's.
So what is exactly PBR?
PBR stands for physically based rendering.
Essentially, it is an approach in computer graphics to mimic how real world materials behave.
Pibor is not a standard way of defining materials and or textures 3D computer graphics industries,
whether it be for video games, visual effects and even architectural visualization.
Because all this time we've been using the physical material, we actually already cover all the basics
of PBR material properties in the earlier lessons, things like Madonna's roughness, etc..
So the next question is where can we get our texture files?
A long time ago to the artists needed to create all the textures manually using the graphics, software
or even 3D printing software.
Now, this workflow is still relevant today for non photorealistic or stylized renderings.
But if you are aiming for photorealistic results, then the best text your source will be from the real
world using the PBR standard.
Nowadays you can get almost every type of BBR texture you can think of pretty easily.
There are at least four or four levels of how you can acquire PBR next.
The first is by simply downloading them.
Many websites provide high quality textures for free.
For example, zero textures, dot com share textures, dot com detections, the m, e, etc..
If the free version of the texture you are looking for is not available, then the second option is
to purchase them.
You can visit websites like Polygon, dot com textures, dot com quicksort, Minkowski, etc..
Based on my experience, paying a small amount of money to purchase these textures are well worth it.
Instead of spending time creating the texture from scratch, you can better allocate your time for other
important things.
If the exact textures that you need are not available, both free or paid, then the third option is
to mix and match existing textures to suit your needs using texture altering software.
For this, you can try substance designer, or you may also want to check quicksort mixer.
There are also free and open source texture altering apps such as Texture Lab, for example.
It is way easier and faster to design a procedure using these specialized software compared to using
general graphics software such as Photoshop or for example, we are not going to discuss how to use
the software as that will be outside the scope of this course.
If the texture that you want to create is very unique and cannot be recreated just by combining existing
textures and you have the real object that has the material, then the less option you want to look
at is utilizing texture digitizer software.
What you need to do is take a lot of photographs of the real material and then fit those photographs
into the software.
The software then intelligently generates the texture set for you.
For this purpose, you can use photogrammetry software, but most of the software are more geared towards
capturing the 3D model data and not really focus on the texture of it.
One software that focuses on capturing texture is substance alchemist.
Although I never use it myself, it's I never really have a need for it.
The software features look very promising.
If you or your organization need to continuously digitize a large number of real work materials day
in, day out, you might want to try and invest in the software from this formatters.
You will end up with a paper texture set that you can use inside through this mix or any other to the
graphics software.
Now, when you browse for texture, you will often see this type of texture that has red logo on its
thumbnail or sometimes just on its logo like these, these are substance texture files.
They use DOT, SBX or DOT SBX are for the file extension.
We will discuss how to use substance textures in another lesson.
For now, we will focus on the general PVR textures that are provided as common image files.
