These effects can be rendered using the bifrost geometry shader delivered with mental ray for Maya 2016.Īutodesk published videos on bifrost and showing mental ray rendering at the end of each: Rendering Bifrost with mental rayīifröst is a procedural framework that can create simulated effects ranging from liquid to foam, bubbles, spray and mist. Light bulb model courtesy of David Hackett. This will turn your geometry into a light. You can assign the new ‘Object Light’ material to your geometry or, with the geometry selected, you can choose ‘Object Light’ from the new mental ray section in the Create|Lights menu. Using custom geometry to light your scene is now possible with mental ray for Maya 2016. There is a new section in the Create|Lights menu for mental ray lights showing modern mental ray lights in a prominent and easily accessible place. The shader is part of a new package called coreutil, which collects essential mental ray utilities and helper functions.

It auto-creates and loads the tile textures into mental ray on demand, making sure that only those tiles that are actually accessed get loaded into memory. Rendering UV-tiled textures is faster and more memory efficient in this version because it is based on a native mental ray shader. It is possible to save deep and simple 2D data into different frame buffers during the same rendering. The resulting image is saved in the DeepTile form of the OpenEXR 2.0 file format, storing additional information of the pixel colors along the Z axis. Mental ray 3.13 adds support for generating ‘deep’ data and output to OpenEXR files. Custom light shaders are fully supported and will be included in importance sampling if they adhere to physically plausible emission and distribution rules. This way, traditional idealized light sources and simple lighting setups can be detected and handled separately, like they may be excluded from importance sampling to retain an overall benefit even though this feature is generally enabled. In addition, new heuristics have been incorporated that automatically determine which light sources in the scene are physically plausible and would benefit from importance sampling. It gives a significant speed / quality advantage out of the box especially with modern and complex lighting setups, emissive objects, and very many light sources. Light Importance Sampling is now enabled by default.

We will provide you with an introduction on how to use MDL in Maya 2016 and with examples for download in this blog soon. Prepackaged MDL materials can be applied in mental ray for Maya 2016. MDL is an NVIDIA initiative to standardize physically based material designs in a common format, see. Mental ray 3.13 renders materials defined by the NVIDIA Material Definition Language (MDL). The Scene tab contains a simplified render passes system for standard utility passesĪs well as MILA Light Path and Matte Pass passes.Ī more throrough introduction to the new Render Settings will follow shortly. For advanced users, each tab provides the ‘Advanced Settings’ mode with more detailed controls to fine-tune the rendering. Five tabs allow to find settings sorted by topic. Settings are greatly simplified and grouped together. Our goal is to make the rendering experience with mental ray straight forward and easy.
