Important notice for Autodesk® Maya® 2012 software, and prior Maya version, users regarding the latest Apple® Mac OS® X operating system release, version 10.7 “Lion”.
Testing Maya 2012, and prior versions of Maya, on the Mac OS X 10.7 operating system, has identified platform compatibility issues.
Installing Maya on Mac OS X 10.7 may cause the installer to hang.
Operating Maya on Mac OS X 10.7 may cause stability issues.
When submitting a crash report while operating Maya on Mac OS X 10.7, may cause the crash error reporting system to hang.
If you upgrade to Mac OS X 10.7, you may encounter these issues. Autodesk recommends that users of Maya 2012, and prior releases of Maya, do not upgrade to the Mac OS X 10.7 until the compatibility issues have been addressed by Autodesk and Apple. Teams from both companies are working closely to resolve these issues and a notification will be issued once the issues have been addressed.
Note: As of this time, Autodesk® Maya® 2012 software has not been certified to run on Mac OS X 10.7. Please consult the certification charts for more information.
Here is the Introduction for users doing Google searches:
Maya 2012 introduces a new set of API classes for defining custom drawing, shading and effects in both Viewport 2.0 and Hardware Renderer 2.0 (the new batch rendering version of Viewport 2.0).
Maya’s Viewport 2.0 represents a brand-new rendering architecture in Maya that has been written from the ground up to deliver high-performance on large scenes on top of a programmable shader system offering high-quality per-pixel lighting and effects. This, unfortunately, makes it incompatible with many of the existing Maya API classes, due to their dependence on system memory geometry data, C++ driven rendering, and high state switching overheads. As a result, most existing plugins will need to be updated to support the new API classes in order to work correctly in Viewport 2.0.
This document introduces the new classes and highlights the migration paths from the old API to the new one. In most cases, it should be possible to write plugin nodes that simultaneously implement both the new and old APIs where required, thus maintaining a single plugin that will work in both viewports while artists, tools and pipelines are migrated to Viewport 2.0.
One of the most important and the biggest changes of the last release (Maya 2012) was Viewport 2.0. I want to take this opportunity to provide you some additional information on the new Viewport 2.0 API. Previously in Maya if you had several high polygon models and you were trying to manipulate those models, Maya sometimes could behave slowly.
Viewport 2.0 is a brand new rendering system it is based on an internal technology by Autodesk. By using this new architecture, we are trying to replace all the old rendering system. As you can see this is a fundamental architecture change. The purpose of the change is to have high performance when rendering large complicated scenes. Viewport 2.0 is much faster compared to the old viewport. Keep in mind when importing this new technology, we have dramatically changed the way shading and rendering works in Maya.
Viewport 2.0 provides a programmable shader system allowing you more flexibility with customization. You can customize a shape, a shader, or a rendering process; it’s all possible with this new system. This new rendering system includes a new viewport 2.0, but also includes a batch version called Hardwar Renderer 2.0. In Maya 2012 there are a lot of new classes in the API. Since some of the new classes have the same name as the old classes, the new classes are in a new namespace called MHWRender.
Every now and than we get requests from users who mention that they have installed True Type Font on Linux but Maya's Create text feature is not picking them up.
The main reason this occurs is because Maya only uses the Type 1 .PFA fonts. These are postscript fonts. So to get TTF format to work you will need to get them converted. There are a couple of tools to get this done.
The first option is simple but involves uploading your current TTF to a online server which converts them and makes it available for download.
