They are straight up unusable for custom map makers if they are locked to one graphics mode and invisble in the others, it’s the same issue the original reforged creators made with new Reforged models for campaign heroes except now we have 10x as many new models and none of them can be utilized because they have only been made for one graphics mode out of three.
This is why having so many graphics modes is ridicolous for a game with such a huge map making scene - even blizzard doesn’t want to account for all graphics modes in their own campaign so how can custom map makers be expected to - the solution is simply to allow overlap between models from different types in custom maps because looking a little out of place is a lot better than not being usable at all.
Edit: Also thanks for the 60 characters limit for titles, definitely enough
