Hi all,
Trying for hours to create a new geode, I'am having a bug I can't fix
Doing
> _root->addChild(createSun(config->Sunpath));

the program crashes
This is the code of "createSun"
osg::Geode* createSun(std::string texturePath)

On crash it return the error:
Exception non gérée à 0x10028b41 (osg25-osgd.dll) dans 3DEM.exe :
> 0xC0000005: Violation d'accès lors de la lecture de l'emplacement 0xfeeefeee

Do you see any mistake ?
Thanks a lot
Regards,
Vincent.
