Add a PBR material.
Material
Method #
This node generates a generic PBR material, which through manipulating its properties can be modified into anything from a rough plastic to shiny metals. The output material can be applied to any node which accepts a material input, such as 3D Objects, Particle Trails, Procedural Meshing.
Parameters
These properties control the core behaviours of the material using Physically Based Rendering (PBR) properties from a A Bidirectional Reflectance Distribution function. Changing the properties below can make a material appear more reflective, more dirty, or add more detail to the material surface. By using textures (either through the relevant inputs, or in the texture section), each of these properties can be modulated over a surface, for more complex material effects.
Parameter Details
Colour The colour of the material.
Brightness How much light the object absorbs and doesn’t reflect back into the scene.
Specular Colour The colour of specular light reflected from the material.
Specular Intensity Intensity of the specular reflections.
Specularity How much specular light is reflected from the object.
Specular Anisotropy Change the shape of the specular highlight.
Emissiveness How much of a glow is emitted around the object. Requires “high dynamic range” to be turned on in the root.
Metallicness Change how metallic the object looks.
Roughness How rough the surface of the material is.
Baked Diffuse Intensity Intensity of the texture supplied via the Diffuse channel - typically used for baked light maps.
Use Baked Diffuse Map As Ambient Occlusion Sets Diffuse Map to become an ambient occlusion map.
Fresnel Diffuse Amount The brightness of the fresnel on the diffuse surface.
Shadow Catcher Colour Colour of the shadow catcher colour.
These properties control how transparent the material is. Transparency isnt always supported with some of the more advanced lighting effects, so some experimentation may be needed.
Parameter Details
Alpha Change the alpha value of the material.
Alpha Mode Change how the alpha image affects the material.
- Opaque : The material is rendered solid, completely occluding any pixels behind it in the view.
- Alpha To Coverage : The material is rendered solid, but alpha values are converted into a dither pattern to allow textured alphas to shape the output.
- Alpha Blend : The material is rendered transparent and the Blend Mode is used to control blending.
Blend Mode Change how the material once added to an object blends with the scene. Only functions with Alpha Mode for details.
Alpha Sort Bias Biases the alpha sorting of the objects using this material, if they are transparent, so they are drawn earlier or later in the sorting order.
Refraction IOR Activates when raytracing is enabled on the root. How much the light is bent through a transparent surface.
Absorption Activates when raytracing is enabled on the root. This is how much light is absorbed on a transparent surface.
Output Alpha In GBuffer Composite Output the alpha channel when compositing. Requires deferred rendering to be enabled on the root node.
Absorption Colour Activates when raytracing is enabled on the root. The colour of the absorbed light on a transparent surface.
Transparent Diffuse Activates when raytracing is enabled on the root. The transparency of the diffuse material.
These properties control a rim lighting effect, a Light which sits just behind the subject and adds a wrapping of liht around the mesh edges.
