Challenge 1: Placing Seams Where They'll Be Least Noticeable — Solution Walkthrough

The answer:

Per this chapter's own material, seams should generally be placed
along edges that are naturally hidden or less visually prominent — an
object's own underside, a character's own inseam — the same way a real
physical box gets cut along specific, unobtrusive edges before it can
fold flat.

Why this specific placement strategy works:

A seam is where the mesh gets conceptually cut to unfold flat, and
that cut location can leave a subtle visual trace in the finished
texture (a faint line, a slight texture discontinuity). Placing that
trace somewhere naturally out of view — underneath an object, along an
inseam that's rarely seen directly — means the seam's own presence
goes largely unnoticed even though it's technically still there.

Why this matters for a character model specifically:

Per this chapter's own material, this is exactly the kind of seam
placement skill this chapter describes as genuinely worth developing —
choosing where to cut deliberately, rather than letting an automatic
unwrap place seams wherever is mathematically convenient without
considering what's actually visible in the finished result.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that seam placement is correctly matched to
naturally hidden or less prominent areas of a model, per this
chapter's own guidance and real-world cutting analogy.
