Ouch! Are you sure it is vertices and not texture ram? Hmmm...I can remember being blown away by the O2's speed first time I saw one, but that _was_ quite a while ago. :-) > Yeah - none of my models could be regarded as low-poly.

That wouldn't be a glitch in the sense of a model data or rendering bug though. Usually if I split something it is because I want a more detailed shape, with a smoother curve. IMO that's a good thing, especially in the hands of someone more skilled than myself :-). BTW do systems that store normal data in the model file not have this problem because you can adjust the shading manually? I do not have experience with anything like that. > The poly count is an issue I've thought about quite a lot but I don't > think I can acheive the same level of detail and smoothness without using > a lot of polys, and as far as sims are concerned there's an irreversible > trend towards greater realism where that detail and smoothness is needed. Yes. If there is enough demand, however, we could scale down the vertices and add a lowres variant of the bigger models to the base package. There is an option right on the ac3d menu to do that. It'd probably be possible to organize the model wrappers so that the same animation xml would apply to both models.
