Lol. I only found the issue because I specifically needed Interjection for Michael5 ... I never thought I’d buy Interjection for M5 and get V4’s instead haha!
Depending on what you’re doing and what you have, wouldn’t it work to use the SSS maps for either M5 Phillip or M5 Dave Elite? Granted, Dave is screamingly fair and would have a tiny bit more translucency than average, but that’s handled in the settings and percentages, not the maps. But in any event, Phillip does have SSS maps (I checked), so you could use those for the equivalent of Interjection’s “light” or “normal” setting. I assume for the sake of argument that DAZ’ own SSS maps should line up, but that I haven’t checked.
Just out of curiosity, which texture are you using Interjection on? I think all the M5 textures except maybe James and Aiden came with SSS textures, although they don’t all apply in Studio the way you might expect.
