The plugins also come with the new vMaterials library: a collection of “hundreds” of MDL assets representing common-real world materials and lights.Īssets from the library can be edited or layered – the system supports up to 16 layers per material – to create custom materials without the need to write shader code. MDL was also introduced in the versions of Iray and mental ray integrated into 3ds Max 2016 earlier this year.įree vMaterials library of real-world materials

MDL materials can be authored using the native tools of the host software: in Maya’s case, supporting UV-based textures and the application’s shading networks. Different renderers and tools interpret the light behavior and create the best possible image.” That not only includes Iray running in different host applications but also mental ray 3.13 and V-Ray.Īccording to Nvidia: “Unlike a shading language … MDL materials define the behavior of light at a high level. The system is intended to deliver “extremely similar results” when displaying materials in any of Iray’s render modes, from OpenGL preview to final-quality output and when displaying materials in different renderers. The major change this time round is support for Nvidia’s Material Definition Language (MDL), intended to provide a standard format in which materials can be shared. Share physically based materials between host software in MDL format Nvidia has shipped Iray for 3ds Max and Maya 2016, the new plugin versions of its GPU-accelerated renderer, adding the option to share physically based materials between platforms in the firm’s Material Definition Language.īoth plugins are developed by third-party firms:, in the case of Iray for Maya 2016, formerly known as IrayForMaya while Iray for 3ds Max 2016 makes use of Lightworks’ Iray+ technology.
