1/ Riptide includes material files with the .obj file. It makes importing Wavefront obj files easier and is a such, for C4D users, a very good plugin. Afaik, Maxon took care the plugin was to be free. 2/ Greenbriar did interest me but apart from some problems with it, there was also a price tag I found exaggerated. 3/ InterPOSER is much cheaper and work fine. It is still in developement, but kuroyume took care to split it up in several levels. The version we now can use is perfectly capable of bringing poser files into cinema. pixelbased textures are perfectly read and transfered but node-based materials and rigging are not there yet. These are for the pro version that is being coded right now. Despite this, kuroyume just recently updated the ltd version we have now to 2.5. Just to show he does not forget to improve what is available now. You also have good and easy contact with the developer himself, and he is open for all suggestions concerning the evolution of this plugin. So for me, there is no doubt. Price/quality, interPoser is by far the winner.

I have tried prudent planning long enough. From now I'll be mad. (Rumi)
