Okay, well I have 3ds Max 6 with a working exporter (I know it works because I've used it.
What format are these files saved as (or just one file with multiple meshes)?
How many require facial animation support? If they have masks they wouldn't need them I suppose.
What program are you using to model with, by the way? (Just curious since you can't export on your own.)
If it's just the weighting and exporting I'll probably be able to help. I've just been weighting my own model and going back to fix problem areas. I've got a pretty good grasp on the weighting aspect. (Also, I prefer to weight the vertices manually. Would that be a problem?)
Would you require them to be weighted only for JA and not JO?
I think that's all the questions I have for now.
By the way, I like the way the models have been turning out. They're looking good.
EDIT: I haven't tried doing facial animation on my model yet (been busy with other tweaks) but I've been planning on including it, so if you needed it done it would only take me a little practice to get that right.
