Below you can find some preset examples:ġ. When you select a Preset Maya automatically set the values for the rendering. Refractions: The maximum number of times a ray can be refracted through non-opaque surfaces. Reflections: The maximum number of times a ray can be reflected off reflective surfaces.Ģ. Raytracing can produce the most physically accurate reflections, refractions, shadows, global illumination, caustics and final gather.ġ. Lowering this value increases sampling which results in higher quality but longer processing time. Anti-aliasing Contrast: This slider controls the contrast threshold. Most images render well with a Max Sample Level of 2.ģ. A higher the number results in a very high quality smooth image. Max Sample Level: This is the absolute maximum number of samples per pixel used when processing an image. Custom sampling is usually the best choice becuse the number will automatically adjust to the number of samples used per pixel depending on the contrast of your scene.Ģ. You can select Fixed Sampling, Adaptive Smapling Default), and Custom Sampling. Sampling Mode: Sampling is the number of times Mental Ray reads and compares the color values of adjavcent pixels in order to avoid jagged lines and display a smooth image. There are 2 important settings that will determine your images quality, Raytrace/Scanline Quality & Raytracing. The quality of the final image depends on the Mental Ray settings, click on the Quality tab on the render settings window. Open the render settings window and and select Mental Ray as the renderer. When the Plug-in manager window opens, check the box Mayatomr.bundle. To load mental Ray go to Window > Settings/Preferences > Plug-in Manager Load Mental Ray in Maya 3D 2012īefore start working with Mental Ray the plug in must be loaded. Mental Ray is also the industry-standard 3D rendering software, used by film, broadcast, & digital publishing.
