alice-teacher Invisible head

[Donald Slater]

Carrie,
Unfortunately, it is not possible in Alice 3 to change any one sub-part of an object, due to the construction of models in Alice 3. In Alice 2, the sub-parts of an object were independent objects, linked together using the vehicle property to create the whole object.

In Alice 3, the models are all one object, with a skeleton of joints to manipulate different parts of the one object. This design choice was made to create objects that would have more realistic animations, (the skin of an object would react more naturally to the movement of the object with this design), but at the cost of being able to manipulate the properties of the “sub-parts”, such as set the opacity.

Please let us know if you have any other questions…

All the best,

Don Slater

I have learned this at least by my experiment: that if one advances confidently in the direction of his dreams, and endeavors to live the life he has imagined, he will meet with a success unexpected in common hours.
