This is a mesh override for the Maxis “Immaculate” shelf (Base Game) that changes the shader to Counters so they will be evenly lit, regardless of what is on them.
I also added three more colour variants while I was at it ‒ white wood, a darker light wood, and plain white (without those bumpmapped lines). Same thumbnail and same model (so the in-game design tool will work for these).
(That little light border between the shelves is on the texture, nothing to do with the lighting.)
Overrides the following:
s4pe, HexEdit // TSRW and Paint.net for the recolours.
