Hi Robert,
I tried without the SmoothingVisitor but it does not change anything.
However during my tests today I put a "Axes" object (the axes.osgt model from
the OpenSceneGraph examples) and some part of the texture on the block below
the object just appeared but really dark.
So it it make me think that it's not a texture problem but maybe a light
problem.
I've tried then to use a full ambiant light:
Code:
osg::ref_ptr<osg::Node> createLightSource( unsigned int num,
const osg::Vec3& trans,
const osg::Vec4& color )
{
osg::ref_ptr<osg::Light> light = new osg::Light;
light->setLightNum( num );
light->setDiffuse( color );
/* full scene lightened: */
light->setAmbient(osg::Vec4(1.0,1.0,1.0,1.0));
light->setSpecular(osg::Vec4(1,1,1,1)); // some examples don't have this one
light->setPosition( osg::Vec4(0.0f, 0.0f, 0.0f, 1.0f) );
osg::ref_ptr<osg::LightSource> lightSource = new
osg::LightSource;
lightSource->setLight( light );
osg::ref_ptr<osg::MatrixTransform> sourceTrans = new osg::MatrixTransform;
sourceTrans->setMatrix( osg::Matrix::translate(trans) );
sourceTrans->addChild( lightSource.get() );
return sourceTrans;
}
int main(int argc, char **argv)
{
osg::ArgumentParser arguments(&argc,argv);
osg::ref_ptr<osg::Group> root = new osg::Group;
root->addChild(createLightSource(0, osg::Vec3(0, -2.0, 0), osg::Vec4(1.0,
1.0, 1.0, 1.0)));
root->addChild(createLightSource(1, osg::Vec3(0, -16.0, 10.0), osg::Vec4(1.0,
1.0, 1.0, 1.0)));
root->getOrCreateStateSet()->setMode( GL_LIGHT0, osg::StateAttribute::ON );
root->getOrCreateStateSet()->setMode( GL_LIGHT1, osg::StateAttribute::ON );
Now the texture appears but are really dark such as there is no light.
Is it something related to states and inheritance?
Thanks,
Florian
