The mod in question is by no means the official art revolution mod. It's just a snapshot of my shader experiments.
I am currently mostly concerned with getting all the models correctly exported. This is not as trivial as it sounds, since WMIT is still in alpha stage and you need to do some manual editing and naming as well.
Since Art Revolution is a group effort, our textures will all inevitably look a little bit different. Therefore we have decided that, before releasing the official mod, all our textures will be remastered, to have a consistent brightness scale and detail level.
We still appreciate any feedback from the community, but I hope this answers some of your questions
