In addition, it's best to start small and fit the texturing process to your own level of expertise.Ĭreating a seamless PBR texture isn't easy, but it can be done. So, if you're looking for more detailed explanations, check out the tutorials on Blender Binge or CG Bookcase. While these steps are easy to follow, they may not be perfect for all situations. However, if you need to simulate the diffuse reflectivity of a concrete or steel material, you will need to generate a separate map. Metalness is a property of certain ceramics. Therefore, you can use a metalness map to create a PBR material that mimics the diffuse reflectivity of a real metal. However, this method has its limitations, especially if you need to blend in deeper pits.įor example, the roughness of concrete will reflect very little light. Alternatively, you can level the texture before blending it. Baking an AO into a texture will help to bring out the self-shadowing effects of plain textures. However, this is not mandatory.Īnother way to achieve a similar result is to use an AO map and bake it into a diffuse map. An AO map can be blended into the albedo of a PBR texture. This will simulate the shadows that are cast by indirect lighting. If you want to add shadow detail, you can also import the ambient occlusion map into a photo editing program. This will prevent weird glares from appearing. Once it's applied, you can set it to blend mode Screen. To do this, duplicate the SM4 height map layer and adjust its opacity to 50%. Typically, it's embedded into the alpha channel of the normal map.Īfter you've extracted the normal, roughness, and displacement map, you're ready to apply them to the height map. It's essentially the main color image of the material. Next, you'll need to use the "More" button to load the diffuse map. It extracts all the necessary information from a photo and translates it into seamless tiling PBR materials. If you're not familiar with PixPlant, it's a great time-saver for texturing. This will give you a complete set of textures that can be used in your project. For this tutorial, we'll skip the more complex Phong map.įirst, you'll need to use a tool like Photoshop or PixPlant to extract the three map files. When combined, these maps will provide a realistic feel to the material. You can also use a displacement map and a normal map. To create a PBR texture, you will need a diffuse, roughness, and height map. The quality of the final 3D scene depends on the quality of the texture. They can be used in all common 3D software. These materials are created from real world photos. PBR (Physically Based Rendering) materials are used in 3D modeling, photorealistic rendering, and feature transfer.
