Hi , tried launching your ShaderDemoProject, doing your step by step instructions but I get error
Fatal error: [File:C:\Users\ernesernesto\Documents\Projects\UnrealEngine4.6\Engine\Source\Runtime\Core\Private\HAL\FileManagerGeneric.cpp] [Line: 613]
Invalid BufferCount=0 while reading …/…/…/…/…/…/Desktop/UE4ShaderPluginDemo-/UE4ShaderPluginDemo-/Content/ShaderPluginDemo/PlayerCharacter.uasset. Pos=3655789018, Size=72724, PrecacheSize=2147483647, PrecacheOffset=3655789018
I’m using unreal 4.6 in Development Win64 configuration
Seems there are something wrong with the PlayerCharacter.uasset 
preventing me to launch the project
