从 Autodesk Account 访问 Maya 或 Maya LT 2019.3 Update。

此页面列出了此更新中的新增功能、更改或修复内容，以及任何已知问题。

新增功能

垂直分割大纲视图
默认情况下，可以拖动“大纲视图”(Outliner)窗口底部的水平分隔条来创建一个分割面板，并在同一窗口中查看“大纲视图”(Outliner)的第二个副本。现在，您可以使用“大纲视图”(Outliner)的“显示”(Display)菜单中新的“窗口布局”(Window Layout)选项，选择使用水平还是垂直分隔条。也可以单击鼠标右键，从“大纲视图”(Outliner)的弹出菜单中访问这些选项。MAYA-103451

使用更新的“大纲视图”(Outliner)关联菜单轻松创建集
现在，您可以使用“大纲视图”(Outliner)关联菜单中新的“集”(Sets)子菜单，从对象创建集和快速选择集，以及创建划分。选择一个或多个对象，在“大纲视图”(Outliner)中单击鼠标右键并选择“集”(Sets)，然后从创建集或编辑其成员身份的菜单项中进行选择。也可以在选择集时自动选择集成员。若要默认启用此行为，请在“首选项”(Preferences)窗口的“选择 > 修改器”(Selection > Modifiers)类别下启用“在大纲视图中自动选择集成员”(Auto-select set members in the Outliner)。MAYA-103453

保留已卸载的名称空间
现在，在创建引用或打开包含引用的文件时，即使您不加载引用本身，也可以选择创建引用的名称空间。只需在选择“文件 > 打开”(File > Open)或“文件 > 创建引用”(File > Create Reference)时启用新的“保留已卸载的名称空间”(Reserve unloaded namespaces)选项即可。 这样可防止名称空间误用于其他节点和引用，导致在最终加载原始引用时发生冲突。MAYA-103504

更改的内容

Maya devkit
pyGroundReflectionRenderer.py 示例中 RenderOverrideOptions 类的 MTypeID 已更改。仅使用随 Maya devkit 一起打包的此示例的版本；请勿复制和粘贴 Maya 开发人员帮助的 Python 参考中记录的版本。如果使用本示例在先前的 Maya 版本中创建了场景，则二进制场景文件将无法在此版本的 Maya 中打开。您需要在早期版本中将场景另存为 ASCII 文件，然后在当前版本中打开该 ASCII 场景文件。MAYA-103573

修复的内容

UV 编辑：Unfold3D 进程错误
Many users on systems with newer, high-end CPUs like Ryzen 3900x series have reported issues and 'Unfold3D Process Error' messages when unwrapping or optimizing UVs. If you run Maya using one of these high performance CPUs, you can now set the environment variable MAYA_USE_ALTERNATE_UNFOLD_SHIM = 1 to use the Unfold3D tools. MAYA-103288

GPU 覆盖 hasAttributeBeenModified 现在可以正确解算
MPxGPUDeformer::hasAttributeBeenModified() will now return true for interactively modified attributes until evaluation of the current frame completes, similar to the behavior of hasAttributeBeenModified() for animated attributes. This improves cases where multiple elements of the aInput and aOutputGeom multi attributes are used in a GPU Override supported deformer. MAYA-100962

已知问题

动画
