This is made from Chuck Walbourn's DirectXTK12 library C/C++ #
I used his old game template download.
The way I solved this problem was to place the vertex and index data in arrays after I changed the data from BigEndian to LittleEndian in a header file. The header file contains only that and bounding data.
I then loaded the data into std:: vector.
I used Hot3dxDrawnObject, Hot3dxGeometry, and Hot3dxVertexTypes header and cpp files from my DirectXXamlToolkit12 at my GitHub site.
Somehow the game is flipped from left to right on the Y Axis. Maybe I can switch the tops of the walls, floor, and sides then view from positive Z?
Or learn how to play it backwards.
