Once the cast is complete, their face will be a realistic representation of their character.
This should be a highly accurate cast, capturing their anatomy as accurately as possible. Then, jump right into the fun of modifying yourself, like making your nose bigger, changing your chin, adding scars or scars, or completely reshaping your face to completely transform them.
It's worth taking a moment to reminisce about the original cast you made of this actor. It's a priceless treasure—it's the only one you have, and presumably, it was acquired at a very high price. Throw it away! Now that the head is perfectly shaped, it's time to create a master mold (usually made of silicone) so that the cast can be produced.
Multiple casts can now be made with harder plaster for later floating/detaching, or a lightweight mold for attaching prefabricated props for painting or transportation (air freight is expensive, you know!). Three people can simultaneously sculpt props on the same nose. A copy can be sent to the actor as a gift. We can even experiment with makeup by applying it to a replica of the head, eliminating the expense of hiring an actor to design the best colors and styles.
This video will explain one method for creating a master mold. Of course, the techniques vary. No two molds are exactly alike, so I'll present the general process I use to create a silicone master mold.
