I can tell you from personally unpacking the assets that it’s a huge hassle to even just unpack them, let alone figure out how to work with them. The only useful stuff I could get were sounds and textures, but without models the textures are useless.
Also, no one had developed tools for Dead Space animations, so AFAIK it’s not currently possible. I could try looking for more information on Xentax, but I doubt it’ll have anything new to turn up.
EDIT: Looking through the Xentax forums, it turns out that the animations are in HKX format (similar to Skyrim and Fallout 4), although it might be a sightly different format. I’ll post again when I have news.
