Sometimes there is an error reported by the logs of Xcode named bind -- Warning: Material parameter 'u_specularColor' not found in effect 'shaders/textured-unlit.vert;shaders/textured-unlit.frag;'.
Does anyone had this problem before?
Is this problem coming from 3D object (i can send you a link), we never had error message from Wikitude 3D Encoder with theses models ?
