Hey,
There are pretty significant changes here from Cloud to UEMHC. A lot of stuff that was a param in the material and subsequently changed via the instance is now exposed in MHC editor and then baked into the textures on assembly as an optimisation step.
It is still possible to change the lipstick colour, or access the spec/roughness maps but there are differences between CloudMHC and UEMHC as detailed below:
Lipstick colour:
-
In Cloud MHC these were material params which could be changed in the Material Instance once downloaded and imported into UE via Bridge.
-
In UEMCH, lipstick colour is set in MHC and is then baked into the baseColor textures during assembly as an optimisation step.
TLDR; Can I change the lipstick colour? Yes, but now this happens in MHC editor, not on the material instance after assembly.
Editing spec/roughness maps referenced by the material instance:
-
In Cloud MHC the texture was \MetaHumans\\Face\Face_Roughness_MAIN
-
In UEMHC it’s basically the same, but named/located here: \MetaHumans\\Face\Baked\T_Head_SRMF (and also utilises the Alpha channel for fake fuzz, which it didn’t before). Exporting that out as .png to modify spec/rough (R and B channels respectively) is still possible.
TLDR; Can I change the spec/roughness maps? Yes, just like before but the texture name has changed between versions, so maybe it’s less obvious which is the correct map.
Hope this is helpful
