If you're a 3D artist, there's a good chance you've heard of physically based rendering (PBR). PBR is a popular technique for creating realistic materials, and it's being used more and more in games and other 3D applications.

One of the advantages of PBR is that it can be used to create materials from real-world textures.

In traditional rendering, the way a surface responds to light is based on its material properties, such as its color, reflectivity, and transparency. PBR takes a more physically-based approach, using the laws of physics to better approximate how light interacts with a surface.

One of the benefits of PBR is that it can produce more realistic results than traditional rendering. PBR can also be used to create a wide range of looks, from highly realistic to stylized.

PBR is often used in conjunction with other techniques, such as global illumination and image-based lighting, to further improve the realism of the final image.

One way to create PBR materials is to start with a texture, such as a photo or scanned image, and then convert it into a PBR material. This can be done in a number of ways, but the basic idea is to use the texture to generate a set of PBR parameters that can then be used to create a PBR material.
There are a few things to keep in mind when converting textures into PBR materials. First, the texture should be of high quality, as the PBR material will inherit any defects in the texture. Second, the texture should be properly prepared, with the right colors and values for the PBR parameters.
Third, the conversion process itself can be quite technical, and there are a number of different methods that can be used. As such, it is often best to use a tool or service that can automate the conversion process.
Once the texture is converted into a PBR material, it can be used in any PBR-compatible rendering engine. This means that the material can be used in games, simulations, and other graphics applications that make use of PBR.
