Loading the Povray project starts up with errors:
I had one issue when I ran
Setup.bat, though, but the build went fine, so I’m not sure if it is related. It displayed the following error:
Failed to download 'http://cdn.unrealengine.com/dependencies/UnrealEngine-4358751-16521f530c414728b289dbb71f593410/80c1ba699c3de9b0950a5521e587025e7f85f8bb': The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters. (PathTooLongException)
Any help or suggestions to fix this would be greatly appreciated.
