Luigi's Mansion- Specular Edition

[Hiryu]

I just tried downloading the custom textures and they seem to load correctly, however, can't get the shaders to show up. Particularly the bloom lighting on all the candles and lights that are so prominent in your video/screenshots. Could you please let me know if there are extra settings I need to change -- using the suggested iishiruka build and also a GTX 970. Would love to get the shaders to work, but can't figure out how.
