Hm, there is no trivial way of doing that, as the OSB Writer currently
doesn't have a good way to pass parameters into to define which of the
two you want. It would be possible to add a filename field to the shader
chunk that would be used in changed() to load the shader. Not a nice
solution, but easy to do. Alternatively you could add a flag that just
defines whether the filename is used, and reloaded in changed().
