You might want to bypass Doga and use a program more capable of creating 3d models for use in-game, rather than just rendering 2d images. Doga can render great 2d images (such as Atrocities' work), but it sucks for games that use real time rendering, as the polygon count of the models is way too high. This will allow you to make models that can be used both in SE4 and SE5. Surely somebody will post links to their favorite modelers.
