In the parameters below, some of them can be overridden by a PxrLayer when connected to the Input Material or through a PxrLayerMixer. It's by combining these lobe settings that you can make just about any material you imagine. However, as different lobes are activated and tweaked, the material will change looks. Pay special attention to notes about performance considerations as well as hints on what combinations will be useful for particular effects.īelow you will find each effect or lobe of the material has been separated into its own section to help users define the area they wish to learn about. We discuss all the different settings and their relevance to making certain materials. Layering provides limitless possibilities.Īs an artist, being able to choose a single material for all your shading eliminates guesswork and allows RenderMan to optimize as needed.Controls are conveniently labeled as "Artistic" and "Physical".Art direction becomes natural without workarounds.Artists can selectively "break" energy conservation.Flexible controls are not required to result in something physically plausible.Physically based presets provided to get you started.A single material handles all your looks like:.As such there are some important benefits to this material: This is the same material model used in Pixar Animation Studios' feature animation. Pixar supports MaterialX in RenderMan 24 and beyond, rendering MaterialX pattern nodes through USD HdPrman, and rendering Physically Based Shading features through a custom implementation of the MaterialX Lama nodes.Īdditional details on MaterialX Lama may be found in this tutorial series from Pixar.Rendering surfaces in RenderMan relies on a layerable material called PxrSurface. MaterialX content can be exported from Arnold implementations in tools such as Maya and Cinema 4D.Īdditional details on MaterialX support in Arnold may be found in the slides from the MaterialX and OSL session at ASWF Open Source Days 2022. NVIDIA supports MaterialX in Omniverse Kit 104.1 and beyond, allowing MaterialX documents to be imported and rendered through MDL shader generation.Īdditional details on MaterialX support in Omniverse may be found in the slides from the MaterialX and OSL session at ASWF Open Source Days 2022.Įpic Games supports MaterialX in Unreal Engine 5.1 and beyond, allowing the import of MaterialX documents based on the Standard Surface shading model.įor now, only a subset of the MaterialX standard data types and nodes is supported, and Epic plans to extend this supported set in future releases.Īutodesk supports MaterialX in Arnold 5 and beyond, allowing MaterialX documents to be referenced and rendered through a custom MaterialX operator. Maya 2024 introduced a technology preview of LookdevX, which supports the creation, editing, and rendering of MaterialX graphs.Īdditional details on MaterialX support in Maya may be found in the slides from the MaterialX and OSL session at ASWF Open Source Days 2022.Īpple has adopted MaterialX as the material representation for its upcoming VisionOS platform, including a pathway for translating Unity Shader Graph content to MaterialX.Īdditional details on MaterialX in Apple VisionOS may be found in the video presentations for WWDC 2023. Karma, A Beautiful Game by Moeen Sayed provides a useful tutorial on look development in Houdini/Solaris, including an overview of using MaterialX to construct surface and volume materials.Īdditional details on MaterialX support in Houdini/Solaris may be found in the slides from the MaterialX session at ASWF Open Source Days 2021.Īutodesk supports MaterialX in Maya through the MayaUSD plug-in, building upon the native support for MaterialX in USD. SideFX supports MaterialX in Houdini 19 and beyond, including the authoring and exporting of MaterialX graphs through the Solaris framework, and rendering of MaterialX content in Karma CPU/XPU. The USD Hydra rendering framework supports MaterialX in HdStorm and HdPrman, using ShaderGen to generate GLSL and OSL shaders from MaterialX graphs on demand.Īdditional details on MaterialX support in USD Hydra may be found in the slides from the MaterialX session at ASWF Open Source Days 2021. Pixar's Universal Scene Description (USD) supports MaterialX through a dedicated UsdMtlx library, enabling the referencing of MaterialX documents and composition of MaterialX content in USD stages.
