Attached Link: V4 in Indigo via Blender

Yeah, without specific knowledge of Indigo, it's going to be hit or miss. You might have better luck going Poser->Blender->Indigo. I'm guessing there are probably more Blender/Poser folks using Indigo than C4D users.

If you want unbiased rendering, Kerkythea via PoseRay is good if you can live with basic Poser material export. The Kerkythea forum is pretty helpful. Tne Poser->Lux plugin may ultimately be the best option.

Really though, if you learn C4D, you may find that you don't need anything else. Unbiased rendering is no magic bullet IMO. While it's tempting to jump around, sticking with one application and learning it well will probably yield better results in the long run.
