The Essentials of PBR Texturing in Blender

PBR texturing in Blender is a key technique for achieving realistic surface materials in your 3D projects. To understand PBR, you should first know it stands for Physically Based Rendering. This method ensures that textures and materials interact accurately with light, imitating the real world.

Firstly, start by gathering your PBR textures. Generally, these include color or albedo, normal, roughness, metallic, and sometimes ambient occlusion maps. You’ll find these maps vital for detailing how light reacts with different aspects of your surface.

Adding Your Shader Node

In Blender, the Shader Editor is where PBR texturing comes to life. Use Shift + A to add a new Shader node, then choose a Principled BSDF shader. This shader simplifies the PBR process by combining inputs for all your texture maps.

Connect the color or albedo map to the Base Color input of the Principled BSDF shader. For the Normal map, you will need an Additional Normal Map node before linking to the shader. This extra step ensures that the bumps and details on your texture affect the light correctly.

Setting Your PBR Properties

The Roughness and Metallic maps control how shiny or dull, and how metallic or non-metallic your surface appears. Connect these to the corresponding inputs on the Principled BSDF. To bring in subtle shadows that add depth, link your Ambient Occlusion map if you have one.

Keep in mind that PBR texturing in Blender is an iterative process. Adjust the strength of your maps and tweak the shader settings to achieve your desired look. The goal is to create materials that feel tangible and behave predictably under different lighting conditions.
