[osg-users] change material of a node but not its children

2008-10-17 Thread Vincent Bourdier 
Hi,

I'm currently on a problem :

I change the color of a node (osg::PAT) but I don't want its child osg::text
to have the same color...

On the PAT I do a
node->getOrCreateStateSet()->setAttributeAndModes(mat.get(),osg::StateAttribute::ON);

On the text :

osg::ref_ptr mat =
(osg::Material*)text->getOrCreateStateSet()->getAttribute(osg::StateAttribute::MATERIAL);
if(!mat.valid())
mat = new osg::Material;


mat->setAmbient(osg::Material::FRONT_AND_BACK,osg::Vec4(0.0,0.0,0.0,1.0));

mat->setDiffuse(osg::Material::FRONT_AND_BACK,osg::Vec4(0.0,0.0,0.0,1.0));

node->getOrCreateStateSet()->setAttributeAndModes(mat.get(),osg::StateAttribute::ON
| osg::StateAttribute::PROTECTED);


The text is in a geode, under the PAT.


Any idea ? thanks a lot.
