Yes...this was the issue. I had the Makeup Pefabs var in a subfolder. @Chokaphi, just FYI, that the referenced VAR also needs to be in the same exact folder as the Decal Maker Var.
For thinks like the Kemeate preset vars and goo var that add prefab/preset to DecalMaker?
That code was written before we have proper file API and is a huge kludge I made to work around it. I will try and get time to see if I can remake/clean it up and get subfolder detection fixed.
I believe that section of code still has the following comment //this is a nasty fucking mess
