Anim8or or Amapi, though I tend to stick with Anim8or. You also need some sort of scaler. The missing trianles thing in Poser is a semi-illusion. The polygon normals get reversed. I've seen it with several models when converted to the .obj format. With the Poser grouping tool it is possible to sort this out without losing any imported grouping/materials info. Assuming you want to sort the visible holes... Open the grouping tool. The display in the Document Window changes. Make sure you have the full display, not the approximate boxes, when you move the viewpoint. Make a new group (you'll delete it later) and select all the polygons. There's a button which inverts polygon normals. Use it, and you get a rather odd effect. But any polygons that were wrong will now appear normal. And they're visible on the outside of the object. Simple to say, but sometimes a big fiddle. Remove those now-normal polygons from the group. Ctrl-click on them. Invert the group. Everything should be the right way around. You can leave the grouping tool and check. When you're sure, use the grouping tool and remove that temporary group from the list. Sometimes, there isn't anything there, but because of the way Poser defines polygon normals, compared to some other programs. a reverse normal is quite likely to be the cause.
