Hi, I have an osg::Uniform::Callback which is working fine with osg::Programm, but I don't get it working with osg::ShaderAttribute. The Uniform Value used in Constructor is correctly passed to my Shader, but the Values don't get update, as if the UpdateVisitor would not reach the Uniform.
osgPPU::ShaderAttribute * shaderAttribute = new osgPPU::ShaderAttribute() ; osg::Uniform * uniform = new osg::Uniform( "Color" , osg::Vec4f( 1.0f , 0.0f , 0.0f , 1.0f ) ) ; uniform -> setUpdateCallback( new UniformCallback ) ; shaderAttribute -> add( uniform ) ; UniformCallback is derived from osg::Uniform::Callback While this code is working ( at another place ) osg::Uniform * uniform = new osg::Uniform( "Vector" , osg::Vec4f( 0.0f , 0.0f , 0.0f , 0.0f ) ) ; uniform -> setUpdateCallback( new UniformCallback ) ; stateSet -> addUniform( uniform ) ; What do I miss ? Thank you!
