Let $\theta$ be a closed $(1,1)$-form and let $\mathcal{X}$ be a SNC model on which $\theta$ is determined. Then each $\theta$-psh model function $\varphi\in\mathcal{D}(X)$ satisfies:

• (i)

  $\varphi\circ\emb_{\mathcal{X}}$ is piecewise affine and convex on each face of $\Delta_{\mathcal{X}}$;

• (ii)

  $\varphi\leq\varphi\circ p_{\mathcal{X}}$ with equality if $\varphi$ is determined on $\mathcal{X}$.
