Metahuman for Houdini's animated maps with Karma/Solaris

Summary

I noticed In Metahuman for Houdini plugin that the animated maps (after animated the head with it’s sliders )are working only in the viewport , but not under Solaris/Karma.
When I use SOP create to build up Metahuman the datas are written to the primvars:material_override as one string, containing the params and their values.
Is there an easy way to connect(and tokenize)these values to their respective shader parameter (through Edit Properties node or something like that)to drive the shader with the animated maps? Now it is not renderable only the default maps are visible on the Metahuman heads.

Thanks in advance,

Ashraf

Steps to Reproduce

simple import and try to render in Karma/Solaris

Expected Result

Metahuman head’s animated maps should be renderable with Karma(or with anything else), animated slider values should be connected to the MtlX shaders in solaris or maybe the controller’s values should be separated primvars on the object (not one string as it is now).

Observed Result

only the viewport shader works

Platform(s)
