MDL out of Substance Designer has difficulties in Substance Painter
I have created a custom MDL shader in Substance Designer, which does work (mostly) in Substance Painter. However, several features that are only availble in MDL 1.6 are used, and those effects do not appear to be working correctly.
Likewise, none of my shader parameters show up in Substance Painter -- I can use user# channels to drive most effects, but settings I might want to change via slider are not available.
Is this a known issue (meaning Substance Painter does not support MDL 1.6 or newer)?
