Yes its essentially the same process, except shaders go into the [EngineDir]\Engine\Shaders (Overwriting the ones there - So don’t use with 4.5 just yet). For blueprint based projects, you will need to add a game module at the very least to your project, and then place the code into the plugins directory as specified above. is to ensure that the can actually be compiled.
I will be porting the to 4.5 very shortly, so I will take some time to write some better instructions for C++ and for blueprint based projects, and for launcher vs. source versions of the engine.
