There is a model I want to use in a movie from tf3dm.com. When I download the model what can I do in 3DXchange to rig it.

Also would I have to buy the Reallusion Facial-Pipeline-Character-Pack to do this or since I have blender do I have to create an armature in there in then import that into 3DXchange?

You can rig them using any of the 3d software.
3dmax, maya, lightwave, modo, c4d, blender. Each one has a different way to rig.
After rigging you can bring them to 3dx to convert to non human for use in iclone.

ok so I don't have to buy the Reallusion Facial-Pipeline-Character-Pack then right?

OK i'm asking if I buy the Reallusion Facial-Pipeline-Character-Pack can it auto rig the model from tf3dm.com site.

In the pack, It said that with one click I would be able to auto rig a model with the default presets.

I know I can rig a model in blender however I was wondering if there was a quicker/better way if I was using the Facial-Pipeline-Character-Pack.

You do not need that pack. It is only useful for DAZ Genesis 1 characters.

3DXChange PRO has the ability to retarget bones. The facial bones are not exactly retargeting to the iClone bones, but instead, set up as morph controllers. You can combine bone and mesh morphs if you want.

See this video:

Im sorry but how will this video help me rig a model? I don't want to rig the face just the body.

When I download the model it doesn't have the bone hierarchy. Its just a prop in a t-pose.

Is there a way to create a bone hierarchy for that prop to convert into a non-standard human?

The facial pipeline pack looks like a reference for proper bone structure and face morphs to use with iclone. It doesn't seem to have an autorigger. So it won't help to autorig characters.
There is an autorigger for blender which you can use then import to 3dx to convert to non human and then characterize.

ok thanks
