osgb文件過大，能夠經過Compressor=zlib對紋理進行壓縮

osg::ref_ptr<osgDB::ReaderWriter::Options> options = new osgDB::ReaderWriter::Options;

options->setOptionString( "Compressor=zlib" );           // 設置壓縮

osgDB::writeNodeFile(*(node.get()), osgb_path, options);

osgconv a.osg a.osgb -O Compressor=zlib

 

 

不起做用的話，添上WriteImageHint=IncludeData
