Hi, well, this code is properly updating my Uniform: osg::Uniform * uniform = new osg::Uniform( "Vector" , osg::Vec4f( 0.0f , 0.0f , 0.0f , 0.0f ) ) ; uniform -> setUpdateCallback( new UniformCallback ) ; stateSet -> addUniform( uniform ) ;
So the update call back does reach the Uniform. My guess is, that you cannot attach the UniformUpdateCallback to an osgPPU::ShaderAttribute, as this one is derived from osg::Programm, but the UniformUpdateCallback is meant to be attached to an osg::Uniform.
