Nitro4D’s Lazaros, aka nitroman has release MagicPreview for Cinema 4D which is a fast way to preview rendered scenes by placing a small preview window window that renders a scene preview in real time so you are able to change materials, lights, and asses an fairly accurate representation of what your final scene will look like.
with magicpreview you can render fast with cinema4d render engine when you make change it’s update , and also you can help to change the mateial lights etc
MagicPreview is for Cinema 4D R13, R14, and for Mac and Windows platforms, 32, and 64, and is donationware, and I do encourage you to read the donationware note on the site which is a great explanation of why it is donation instead of freeware.
Joren Kandel of the PixelLab has also created a little demonstration of how MagicPreview works within Cinema 4D of which you can find here.

Probably the best plugin I’ve seen for Cinema 4D. Good lord!
