Because at the moment iclone's compatibility with Cinema 4D and Redshift is súper.
You just have to conect the transparency to the opacity and you're all done. Just render.
One iclone character only recquires one minute of work un C4D, SO a scene with 10 characters would only need around ten minutes of your time for 'adapting' your iclone characters to C4D and render in Redshift,,, which is pretty and fast.
In Maya tales around 2 hours or maybe more,,, beautiful result buuuutttt time consuming.
