Hi there I noticed a limitation in TexGen. It looks like osg::TexGen can only be used up to a texture unit between 0 and 3, starting from texture unit 4 to 7, osg::TexGen have no more effect. You can easily test this with the osgspotlight.cpp example by changing the following lines:
Line 249: xform->addChild(createSpotLightNode(osg::Vec3(0.0f,0.0f,0.0f), osg::Vec3(0.0f,1.0f,-1.0f), 60.0f, 0, 1)); replace the last number (1). Line 275: root->setStateSet(createSpotLightDecoratorState(0,1)); replace the last number (1). If you use numbers between 0..3, everything works fine, 4 and up doesn't work anymore. Where does this limitation come from? Is this OSG or opengl? Regards Daniel
