elizabethtasker, Today.... we're simplifying this ceiling light! This is about 33,000 polygons, but (being a ceiling light) you never stand close enough to really examine the detail.
By creating the vertical notches with a texture, I think I can re-create this with about 1,500 polys. My pre-textured shape is the grey clone above the original.
I just hope it casts similar light shadows (which are quite cool).
