To achieve this realistic look, a PBR texture is usually composed of several different texture maps, which include information describing the material’s color, reflectivity and roughness, depth and height, and even how the material handles ambient lighting. For example, most metal materials reflect a lot of light, while surfaces such as concrete reflect very little light, making their surfaces look flat and matte.

What exactly is a PBR texture? How do they help 3D artists create photorealistic images in applications like Blender, Cinema 4D, Maya, Unity and Unreal Engine? PBR or Physically Based Rendering attempts to simulate how materials behave in the real world, specifically how they reflect and absorb light.

However, when you’re pressed for time or are more interested in other aspects of the process, using free textures you can find online is usually sufficient, especially if you’re still learning. 8 Awesome Sites for Free Blender TexturesĬreating textures from scratch is often a very satisfying job.
