Hi Tyler,
Not so sure about textures - so they display, but upside down? Perhaps
it is an issue with vertex ordering (clockwise vs. anti-clockwise). I
had building models (3D Multipolygons) where the models were rendered
inside out. According to Martin Dobias, this is an issue with vertex
ordering, and I do hope that when QGIS 3 is shipped, that there will be
an option to set the vertex ordering with a checkbox or radiobutton.
As to the 3D raster DEM: this definitely works. In the 3D view you have
to press the "Configure" button in the top-left of the 3D window - the
button with the screw-wrench. In the dialog that opened you can choose
the raster layer with the DEM.
Depending on the size of the DEM, the triangulation of the raster DEM
may take a few seconds.
Hope this helps and greetings,
Andreas
