Exposed parameters in exported mdl

[andrew.cirillo]

Hi,
I just have a question about exposed parameters in exported mdl materials. I noticed that parameters that I expose in mdl networks where the root node is a custom mdl package (which has exposed parameters itself) that none of the parameters are exposed when I export the mdl package. Is it not possible to construct mdl in this way and still have exposed parameters in the exported mdl?

Any chance of a response on this? Is it a bug?
I have a project that requires a large number of mdl resources to be made, and I wanted the base MDL to be modular and then just hook in exposed colour nodes or substance packages. This way I could make changes to the base mdl and effect all of the materials if needed. However this currently does not appear to be possible.
