[QGIS-Developer] PostGIS 3D cube lacks vertical faces

[Andreas Neumann]

Hi Anita,

Have you tried changing the "Culling" settings in the 3D rendering 
properties of the layer

It might solve your issue. Some systems use clockwise, some 
counter-clockwise ordering of vertices describing a face. For that 
reason you can change the culling setting per layer.

It is, however, a relatively new enhancement and may not be available in 
your build, if it is several days old.

Greetings,

Andreas
