Abstract: We show that the $C{P}^{N}$ model with an odd number of scalar fields and a $\mathsf{V}$-shaped potential possesses some finite energy compact solutions in the form of $Q$-balls and $Q$-shells. Such solutions were obtained in $3+1$ dimensions. The $Q$-balls appear for $N=1$ and $N=3$, whereas the $Q$-shells are present for higher odd numbers $N$. We show that the energy of the solutions behaves as $E\ensuremath{\sim}|Q{|}^{5/6}$, where $Q$ stands for the Noether charge.
