I can share here too because it is only a sample from "unknown" location: https://community.esri.com/servlet/JiveServlet/downloadBody/8672-102-1-10779/Cylinder.gdb.zip
I hope the URL working.
It is a simple cylinder with 36 sides (36+1 vertex on the top and 36+1 vertex on the bottom, constructed as TriangleStrip, where the "+1" is the closing vertex) created by the GeneralMultipatchCreator CoClass from ArcObjects. Each vertex has texture coordinate, no normals included. The coordinate system is EPSG 23700. The problem is quite simple: I can’t zoom in enough to see the geologically important details of the texture. (The gray line is an orientation marker on it.)
