Never mind. It works now by using the same technique as for the
SGMaterialAnimation where a group is placed in between the object whose
texture should be changed and its parent. This group overrides the texture:
stateSet->setTextureAttribute(0, _new_texture,
osg::StateAttribute::OVERRIDE);
stateSet->setTextureMode(0, GL_TEXTURE_2D, osg::StateAttribute::ON);
If there exists a faster method which doesn't require the additional
group, please tell me.
Regards,
Tom
