Well, I decided to try out the Vampire origin, but I found out that I am not getting the night vision described in the origin details.

I tested under the following conditions: the sky is clean, I am not under any blocks, it's a full moon and I tried out both ability toggles. Still did not get the vision.

I don't know what I could be missing so I think this is most likely a bug.

Edit: I forgot to say I am also running the version 0.7.1 of the mod.

Well, I was missing something. Seems shaders do not play so good with these details. Closing this issue now.
