That is because they are "ripped right out of 2002". They are the exact same geometry as they were in Warcraft III. Only some models have been updated, not all.The ones showcased by Blizzard beforehand looked as expected. But those ships above look ripped right out of 2002.
LAN option, playing maps vanilla BNet style (create your own game from a local mapfile of your choice), not having to log into your BNet account to use the editor, just to name some.
They will fit with most of the WC3 assets very well. They will not fit with the SC2 assets well. This is because they lack specular and normal maps so will appear noticeably out of place.I've been thinking: perhaps the models used for the Ultimate Terraining Map would fit well in SC2?
This actually would be a fantastic idea, converting the HQ models from SC2 to WC3. I remember Blizzard saying something about converting certain models being illegal though, or was that just for World of Warcraft?
I'm sure that you're free to port them from sc2 to wc3 without reprisal. WoW and D3 models are certainly free to use. Blizzard has hinted that they wouldn't be too happy for sc2 maps to use Heroes of the Storm models, but a few are doing it anyway and haven't been banhammered.
TL;DR it'll be fine for sure.
It's worth noting that the models are a bit rough when it comes to attachment points though. You can get around this in sc2 but wc3 is a lot more rigid when it comes to such things. Auras and some overhead buffs may not display in the right place or display at all, but if that's not a problem then the models will be fine!
I'm surprised, I remember from a while ago that someone got in a bit of trouble for using a converted model of a dragon from World of Warcraft but it might have been from another game I'm not too sure.
Blizzard does not mind. You can use any of their models in any of their other games as they own it and are not going to sue themselves. They have on multiple occasions for both WC3 and SC2 highlighted Arcade games using resources from other of their games with grate praise. This is why the "no WoW port" rule was removed under my recommendation.This actually would be a fantastic idea, converting the HQ models from SC2 to WC3.
