I know, but when I place a model in the editor, it is the old models, not the new HD models released by blizzard. When we play through SC2, we can choose to play with the new or old model. I want to simply always have the new models.
Also, for the races, it has to do with question 2. When i do select any of the blank race options, its still zerg/terran/protoss, and not the warcraft 3 races. I imagine its because the units are not associated with their respective race.
Not every unit has hd models, Multiplayer Heroes and units that spawned by multiplayer heroes units have, and a lot other have too, but not all of them. You can change the referenc path in models. Tyrande and Arthas have HD in default, Uther has normal, but there is paladin HD model in war3 mod. I have 12 race in default Crace(the example), Creep, Critter, Human, Orc, Naga, Neutral, Night Elf, Protoss, Terran, Undead, Zerg.
