[osg-users] [VPB] Multiple textures

[Robert Osfield]

Hi Rahul,

VPB/osgdem supports multiple texture layers via the --layer <num>
entry, just prefix this in front of the texture specification for each
layer.  The layers go from 0 upwards.  The scene is decorated with an
osgFX::MuiltiTextureControl node.  The osgmultitexturecontrol example
in SVN/2.3.6 can be used to view them.

Robert.
