Support asset/morph asset is depricated...
So, how do I now save Head Split morphs? Is it "figure/prop assets" or "save modified assets"? And, if it is "save modifified assets", where do I find these assets once they've been saved so they can be applied to a character?

If you want to save a morph it is Save As > Support Asset > Modifier Asset and select the morph you want to save.
Okay, thanks. I'm gonna assume uncheck everything except the head split character head/body morphs and then save? Or just save as the dialogue box opens?
Uncheck everything, except what you want to save.
If you save all, you will get duplicate formulas.
