i guess that you had a fail in the custom made model in the exporting time. are you sure the models (all of them,objects,not dummies) have skin modifier? if they dont have skin modifier at the exporting time it is your fail. GIMS dont review the modifiers (only if its a box ,cilinder,plane....)it only exports editable mesh and editable poly.(and skin)
here is what you have to do.
1.import the original model again (inside your modded model scene)
2.copy the original object's modifier(should be "skin")and paste it to the modded one
3.delete the original model and all the stuff it contains and export again.
anyway, how does the model walk in game? did you make a test? or your game didnt even started?
it should be all right but if you have any problem just let us know. This post has been edited by aacclapd on Thursday, Jul 5 2012, 21:39
