Incorrect conversion of the OSG polygonal paged database
A database created using VirtualPlanetBuilder with the --POLYGONAL option and georeferenced texture could not be converted to vsgt/vsgb. There are artifacts and no texture.
I have tried many combinations of parameters, different versions of VSG and vsgXchange, alternative texture formats, alternative image compression, I have created both osg binary databases and ascii databases. But if I add a texture to the polygonal database everything stops working.
database generated with following setup:
osgdem --POLYGONAL --compressor-nvtt-nocuda --geocentric -d /dems/in -t /dems/texture/referencedl.tif -o /dems/out/database.osgb
VPB from 'master' OSG 3.6.4
osgviewer:

vsgviewer:
converted root file: database.txt
one of the subtiles: database_L5_X8_Y15_subtile.txt
P.S. A polygonal database created without any texture is working fine.
I don't know what to do in this case, vsgviewer does not give any errors.
Would it be possible to provide some reference data so I can reproduce your exact test?
