Sounds promising!
Always nice to see that people are still creating mods for amnesia.
As for: "
Expect to see a mixture of realism and fantasy. So lighting might not be what you're expecting." you still might want to consider adding a bit more light to your maps. Good lighting can greatly improve the looks and depth of your map. I suggest adding a dark box light (set the R/G/B values to something like 0.07 / 0.07 / 0.07) to erase pitch black spots in your map.
For lamps I recommend adding a point light with a bigger radius than the one of the lamp but with less brightness. This creates a more realistic look and will give the player the opportunity to actually be able to see your new models
I'm looking forward to see your mod finished, keep at it!
