Autodesk Maya2020.4 is a new version recently released by Autodesk, and it is also the best 3D animation, modeling, simulation and rendering software in the industry. Autodesk Maya2020 [☜borrow your finger to use] provides a powerful integration The combination of tools can be used for animation, environment, motion graphics, virtual reality and character creation, which can easily help users develop the 3D works they need. At the same time, the software also integrates the most advanced animation and digital effect technology of Alias and Wavefront, which not only includes the functions of general 3D and visual effect production, but also is compatible with the most advanced modeling, digital cloth simulation, hair rendering, and motion matching technology. In combination, interactive hair combing is used to support the generation of realistic hair and hair clumping effects to obtain more natural-looking hair and fur. With this new adaptive solver for Bifrost liquid, the software can simulate advanced details only where needed, so that users can better produce their desired works.
In addition, the new Autodesk Maya 2020.4 version has received a series of upgrades and optimizations on the original basis, with the Bifrost extension for Maya 2.2.0.0, support for more powerful Maya integration, and improved usability As well as new functions such as scattering, instancing, volume and FX, it also provides MtoA 4.1.1, which can present the Bifrost terminal and the new bifrostGraphShape, and includes the functions of MtoA 4.1.0, such as the imager, and a new post-processing framework. The new version supports nested dielectrics, greatly improved progressive and adaptive sampling, etc. At the same time, Maya 2020.4 updates the Rokoko plug-in, with a new Rokoko motion library plug-in. The plug-in includes an improved initialization experience, enhanced character preview with new track functions, and other bug fixes.
