hey,
first of all: extraordinary work, ! 
The github project works just fine for me when I used UE4.16; for UE4.17 however I get some errors, like e.g.
“SetBlendState is not a member of FRHICommandListImmediate” in PixelShaderUsageExample.cpp
Can someone update the project for UE4.17 or give some hints how to do it (I couldn’t find any messages about a deprecated SetBlendState function or which function replaces it)?
