Battle for Bikini Bottom Rips

I think they're suggesting 3DS Max and Blender because they have more features that you can use to fix your models, either that or they're saying that they'd only be able to help you if you had one of those since they don't use Misfit Model 3D or Milkshape.
I couldn't help you at all either since the only program I really know how to use is Cinema 4D Studio.
Does Misfit Model 3D actually have the ability to fix your models the way you need to though? There is another TSR member who is good with it I think so if it's technically possible then I can ask him to look at this thread.
