Hi All,
I would like to set a color to a node that comes from an obj file (attached).
Here is the code I tried. You can simply use it in whatever OSG example.
Code:
osg::ref_ptr<osg::Group> root = new osg::Group;
osg::ref_ptr<osg::Node> scene = osgDB::readNodeFile("wheel.obj");
if (scene.valid())
{
root->addChild(scene.get());
double rgba[4] = {1.0, 0.0, 0.0, 1.0 };
osg::ref_ptr<osg::Material> material = new osg::Material;
material->setDiffuse(osg::Material::FRONT_AND_BACK, osg::Vec4(rgba[0],
rgba[1], rgba[2], rgba[3]));
root->getOrCreateStateSet()->setAttribute(material,
osg::StateAttribute::OVERRIDE);
}
viewer->setSceneData(root);
The problem is that only some parts of the wheel are red (see attached png
file).
Could you please tell me what should I do to color the wheel completly?
Regards,
Gianni
