1) Where are the caverns?
2) People will complain about so much orange, better to use the grey reflectivity textures
3) 96 cubemaps is waaay more than you need for an alpha map. You could probably get away with less than 5, even.
Answers: 1) The first alpha made a tad more sense, and I am planning to change the name later on.
2) OK...? I will change them sooner or later.
3) I can just remove them, i made a visgroup for them.
I will be answering most questions for this map, other than ones requesting area to be added in-map, for example, another room, unnecessary from the map.
