For example, you may have loaded a new scene and no EG may have been built yet, or you may have changed your scene, invalidating a prior EG.

A valid EG may not exist or become invalid for various reasons. EG connections represent node-level dependencies destination nodes employ data from source nodes to correctly evaluate the scene. The EG is a simplified version of the Dependency Graph (DG), consisting of DG nodes and connections. Prior to evaluating your scene, the EM checks if a valid EG graph exists. The EM schedules EG nodes across available compute resources. For now, letвЂ™s focus on understanding key Maya evaluation concepts.ДЄt the heart of MayaвЂ™s new evaluation architecture is an Evaluation Manager (EM), responsible for creating a parallel-friendly description of your scene, called the Evaluation Graph (EG). As you can imagine, the amount of parallelism depends on how your scene has been constructed. Similarly, if your scene has a single complex character, it may be possible to evaluate rig sub-sections simultaneously. For example, if your scene contains different characters that are unconstrained to one another, Maya can evaluates each character at the same time. Unlike previous versions of Maya, which was limited to node-level parallelisms, Maya now includes a mechanism for scene-level analysis and parallelization.

Starting from Maya 2016, Maya accelerates existing scenes by taking better advantage of your hardware. If you would like an overview of related topics prior to reading this document, check out Supercharged Animation Performance in Maya 2016. This guide will be of interest to riggers, TDs, and plug-in authors wishing to take advantage of speed enhancements in Maya. It covers key concepts, shares best practices/usage tips, and lists known limitations that we will aim to address in subsequent versions of Maya. See What's New in API in Maya 2018.This guide describes the Maya features for accelerating playback and manipulation of animated scenes. Numerous improvements have also been made to Bifrost and Animation to expand their capabilities when working with foam and time formats respectively.ДЇor plug-in developers, Maya 2018 includes a number of important updates to the Maya API. Try combining them with the new primitives, which allow you to create complex organic shapes and animate them on the fly. New MASH Dynamics allow you to apply dynamic properties to MASH networks, which stack with existing MASH nodes to quickly create visually stunning motion graphics with just a few clicks. Arnold 5 is included with your installation of Maya, and includes features such as new physically based surface, hair and volume shaders, new utility shaders, support for light group AOVs and light path expressions, and improved color management support. Additionally, enhancements to the Render Setup system make it easier to create and adjust collections and overrides, as well as sequence and batch render. Updates to Viewport 2.0 that make it compatible with OSD 3.1, complex shading networks, displacements, light shadows, and ambient occlusion, provide a better realtime idea of what your rendered images will look like.

Meanwhile, general workflow improvements and a new Shaderfx Game Hair shader now make this the ideal tool to create hair for game characters. Together with enhanced global symmetry support all throughout Maya, as well as improvements to Quad Draw, Multi-Cut, and Live objects, you can now create and texture models faster than ever.ДЄ new clumping modifier makes Interactive XGen grooms more natural by breaking up uniform flow, while a collision modifier allows hair to react to other meshes (such as hats). The new UV Editor modernizes the UV workflow, giving you powerful tools to create UV layouts with ease. This release includes major workflow improvements and new features aimed at making content creation easier than ever before.
