This week focused on how to correctly apply textures to a model and turn them into reusable materials. In practice, textures do not work as independent assets. Instead, they are organised and interpreted through the Material system, and then displayed on the surface of a model.
In UE5, textures usually exist as Textures, such as Base Color, Normal, Roughness, and Metallic. These textures do not affect the model on their own. They only contribute to the final render when they are connected to the correct input slots in the Material Editor. For this reason, the first step is not simply dragging textures onto a model, but creating a material and understanding the role and position of each texture within it.
The Material Editor starts with a blank Master Material Node, where you’ll connect textures and nodes to define your material’s appearance. Key inputs for a standard Physically Based Rendering (PBR) material include Base Color, Metallic, Roughness, and Normal.
Essentials:
- Base Color (Albedo/Diffuse): Defines the surface color under neutral lighting, without shadows or highlights.
- Normal Map: Adds the illusion of surface detail without extra geometry. A flat plane with a normal map can appear to have surface detail as if it were modeled.
- Roughness: Controls how smooth or rough a surface is, affecting light reflection.
- Metallic: Determines if a surface is metal or non-metal. Metallic textures use black and white values, with no in-between unless specified by a texture.
Once the material is set up, it can be dragged onto a model in the scene, and the surface result appears immediately. This instant visual feedback is one of the key advantages of UE5’s real-time rendering workflow.
For finding suitable materials and textures
Fab provides a large library of ready-to-use models, materials, and texture assets. These resources are very useful for learning and for project work, and they can be installed directly into a project.
