In UE4, the height map is used to determine the height or depth of a pixel, with white being zero depth and black being maximum depth. Parallax occlusion mapping (POM) is a technique for creating definition in a Material by displacing an Object's UVs and simulating depth within a texture plane. This ensures material size consistency and provides accurate tiling:Įach Material also handles UV rotations properly: Since triplanar mapping is based on positions, each Material can use the actual physical size of an Object. The image below illustrates how triplanar mapping uses planar maps projected along the X (red), Y (green), and Z (blue) axes to create a complete procedural UV projection with minimal seams or stretching: Materials keep the same texel ratio when Objects are scaled. It uses local space positions to avoid textures appearing to slide across the surfaces of the Objects. This triplanar mapping function has several useful features:

This means that you can use all Materials successfully on Objects that do not have UVs, as is often the case for parts that come from CAD applications. This is the default behavior for all Materials in the pack. Instead, triplanar mapping applies the texture map to three orthogonal planes, then projects these three planes to the surface of the Object. Triplanar mapping is a way of applying texture maps to an Object that does not use UV mappings to map the Object's 3D surfaces to a 2D texture space. The pack includes a material function that performs efficient triplanar mapping.

Rougher surfaces, where the roughness map is closer to white, have blurrier, less distinct reflections.įor a more in-depth explanation of what physically based rendering is and how to use it in UE4, see the Physically-based Materials documentation. Smoother surfaces, where the roughness map is closer to black, have sharper, more focused reflections. The Roughness map controls the glossiness of the surface. The Specular value is typically left at the default value of 0.5. The Specular input is not exposed in any Materials to avoid introducing any reflections that do not accurately match the behavior of light in the real world. This ensures that all surfaces reflect a physically accurate proportion of specular and diffuse light. This is determined by a node in the Master Material, exposed to Material Instances as a single IsMetallic checkbox. Similarly, all Materials in the pack are either fully metallic or fully non-metallic. In the real world, almost all surfaces behave either as a metal or as a non-metal (dielectric). Inside of the Twinmotion Material pack you will find the following Materials types:Īll Master Materials in the Twinmotion Material Pack are original materials built to achieve the most realistic and accurate results possible with Unreal's Physically-based Rendering system. For more information on Materials and their use, read the following documentation: The Material Instance exposes these parameters and gives you a way to create multiple variations of a Master Material quickly.Ĭreating and using Master Materials in UE4 is an advanced workflow. These Material Instances are created from a Master Material, which contains several properties that have been designated as parameters. In UE, an instance of a Material can be used to change the look and properties of that Material without requiring an expensive recompile. Finally, every Material is optimized for a variety of lighting solutions and is ray-tracing ready. Parallax occlusion mapping is used to procedurally generate brick and tile materials. Every Material follows physically based-rendering best practices, and all are designed for ease of use. The Twinmotion Materials pack provides 3D visualization professionals with a state-of-the-art collection of Master Materials and example content for creating remarkable indoor and outdoor spaces. Utilizes the latest parallax occlusion mapping (POM) techniques to procedurally generate materials such as brick, concrete blocks, ceiling tiles, and cobblestone.įull support for all lighting methods, including ray tracing.

Support for both Object UVs and triplanar mapping even when models have imperfect UV mapping. All materials utilize PBR best practices.īased on the popular Twinmotion asset library and utilizing the Quixel Megascans library of hand-scanned 2D assets. Based on the Twinmotion asset library, this assortment of materials features:Ĥ97 Materials Instances, driven by 10 Master Materials. The Twinmotion Materials pack, available on the Unreal Engine Marketplace, is a collection of architectural visualization-themed physically based Materials ready for use in Unreal Engine (UE).
