Autodesk Maya 2018.7 Update Release Notes:
What's Fixed
In addition to the issues listed below, this release includes two important fixes:
UV Editing: Unfold 3D Process Error (MAYA-103819)
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.
Viewport 2.0: Run in OpenGL Core Profile mode with Windows Remote Desktop Connection (MAYA-104308)
For the most part, you can run Maya normally over Remote Desktop Connection on Windows. By default, this configuration forces Viewport 2.0 into DirectX 11 mode.
If you have an Nvidia GeForce graphics card and you want to use OpenGL mode instead, Nvidia has released a new tool to enable Windows Remote Desktop streaming of OpenGL applications with GeForce drivers R440 or later. To use this tool with Maya 2018.7, set the environment variable MAYA_ALLOW_OPENGL_REMOTE_SESSION=1.
