I have slllooowwwlllyy (slowly) been working on a persona project of a realistic animatronic werewolf. Unfortunately the two part mold that I used formaking his skin got broken - the inner part shattered and having already made an underskull from it I was faced with the problem of remaking it AND ensuring that all of the skin thicknesses were the same.
Sure I could do multiple pours of silicone and waste a ton of money fine tuning the inner mold but I really needed something that is translucent, reusable, and inexpensive.
Someone suggested Gelatine so I made up a batch using the formula from Todd Debreccini's book (if you don't know that one - get it - it's a bible for SpFx)
Anyway - Here are my results and I am very happy. I pulled it apart before the Gelatine had totally cooled but it's still great for reference.
Now I can add shims and sections it lessen the skin thickness
