Hi JS, I'm surprised that you are seeing this warning as for a 32bit build the void* should be 32bits and GLsizeiptr should be 32bit. When under a 64bit build the GLsizeiptr should be 64bit. Even if GLsizeiptr was 32bit and void* was 64bit one should still be able to cast it safely, the

Re: [osg-users] split scene into separate nodes/files.

Hi, As far as I understand, but the WorldMatrix resides in the MatrixTransform node which is farther of Geode so when I'm getting Geode I'm actually saving its farther (MatrixTransform) The Geode is currGroup-getChild(i) And the farther is CurrGroup which I also tried to save.
