Sorry for not having noticed your post earlier. In order to get an
hexagonal patch, you need to use "WrapNearest on".
The vectors I use are the following:
v1 = ( r ; 0 ; 0 )
v2 = ( r/2 ; sqrt(3)*r/2 ; 0 )
v3 = ( 0 ; 0 ; h )
With r being the inner radius of the hexagon and h the height of your box.
The Hexagonal patch has to be oriented in such a way that it's centered
in the origin and with two sides perpendicular to the X-axis.
