Somewhere on Internet I came across a piece of writing, where it said first sculpting is done, the retopology. Then the retopologized mesh is sent to animator.

After that it is sent back to sculptor. The new posed model is again sculpted for details.

But my question is

1. Is the retopologized mesh sent to animator before normal baking?

2. If baking can project details from sculpting to the retopologized mesh, why there is the need to sculpt it again for details after it returns from animator?

3. Animation is not a single pose. So how the second details is projected?
