Try replacing with x3d_ for cobweb, and declaring them in the shader (I don’t think it will work otherwise, but I could be wrong). You will probably have to provide modified shader code in addition to the normal glsl shader. If providing an alternate URL for cobweb will work, I would do it—I am unsure what would happen. We may have to provide an alternate URL for each X3D vendor.
