SkyBox Pack Sci Fi

At a loss as to what the creator had in mind on these. 1st the use of the term "mod" is as loose as one could use as its a single mesh so no way of creating an entrance if one needed too or anything else other than increase or decrease the size. 2nd the edges of the panels look like the teeth on a wood saw. 3rd the land impact count for a simple mesh like these is almost the same as if it was made from prims and convex hull used. 4th the pyramid is non trans, one of the texture is non copy. A major disappointment.
