Hi Ulrich
I think you are right in what was going wrong but for some reason the prox node
does not complain when I delete the file and rewrite it, the key is to delete
it first. The material-modified models can be saved and reloaded with this code:
Code:
void M_model::Update_files(void)
{
if(_material_changed)
{
if(boost::filesystem::exists("../Models/" + _file_name + ".osgb"))
{
boost::filesystem::remove("../Models/" + _file_name + ".osgb");
}
if(boost::filesystem::exists("../Models/" + _file_name + ".3ds"))
{
boost::filesystem::remove("../Models/" + _file_name + ".3ds");
}
osgDB::writeNodeFile(*_prox_node, std::string("../Models/" +
_file_name + ".3ds"));
osgDB::writeNodeFile(*_prox_node, std::string("../Models/" +
_file_name + ".obj"));
// osgDB::writeNodeFile(*_prox_node, std::string("../Models/" +
_file_name + ".stl"));
}
}
Thanks,
Patrick
