I highly doubt Blizzard would include wc3 models in starcraft2. However, if they still use the mdl/mdx format, it may not be too difficult to import the models into sc2 with or without some modification. If not, you can expect there to be third party software that will convert the format, you can almost be certain of that. However, the only issue with putting a wc3 model in starcraft2, is the difference of polygons, and qualities. The animation sequences are probably a bit different as well. A wc3 model may look a bit awkward in starcraft2, but I wouldn't be surprised to see it. People took WoW models, and modified them for Wc3. There will always be people who will make mods for map making, it has been the case with wc3 and without doubt will be the same case for sc2.
StarCraft II uses .M3
Each model uses like 3 .dds texture files. (around 3, specular, diffuse, and normal).
There will be StarTools which can convert from 3ds max to the format that SC2 uses. I imagine a lot of WC3 models can be converted this way, but new textures have to made for them.
Hm, interesting. Still, there will be third party software that converts this stuff. Though, it would be important to improve quality of the models to avoid it looking like Super-Mario Bros sprites in Call of Duty.
Its not being done. Blizzard wrote that they won't convert wc3 models to sc2. You might have read it wrong or the person who wrote it read it wrong. Its the same reason why WOW models can't be converted to wc3 without special programs made by hackers.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
