[osg-users] [vpb] Doubt regarding integrating shapefile with VPB

[Vinoth Rajendran]

Hi Community,

I have builded a terrain database with shapefiles associated to that terrain region using VPB. I noticed that the generated .osg file has height data for shapefiles. When i load my osg file into osgViewer , it renders only terrain height map data. 

command used to generate terrain database is:

Code:
osgdemd -d terrain.tif --building build.shp -o data.osg



Why shapefile  data not getting rendered with height ? Below i have mentioned snapshot of osg file with shapefile associated datas
