Ok I just tested this in Affinity Designer 2.5.5 and it works beautifully! It does prompt me that saving the template will update it to work only with Affinity v2 (and not Affinity v1), but for me, that’s not a problem.
Thank you for opening my eyes to a fantastic way of setting up hexagon grids in the Affinity suite, because it’ll definitely help me make some of the hex games I’ve been working on in Designer!
