PBR, or Physical Based Rendering, is a technique used in computer graphics to accurately reproduce the appearance of real-world materials. It involves using complex algorithms to simulate the way light interacts with different surfaces, taking into account factors such as roughness, metallicness, and specular reflectivity.

One of the key components of any PBR workflow is the use of high-quality textures. These are images that are mapped onto 3D models to add realism and detail to the final rendered output. While there are many commercial texture libraries available, there are also a number of excellent free PBR texture resources that can help you get started without breaking the bank.

Here are the top 5 free PBR texture resources:

  1. CC0 Textures: This is a website that offers a wide range of high-quality PBR textures that are licensed under the Creative Commons Zero (CC0) public domain dedication.
