RealFlow's “Connectivity Plugins for Cinema 4D” contain a set of tools to establish a bridge between both programs. The data, written by RealFlow, cannot be loaded and processed in Cinema 4D by default. Cinema 4D's object geometry, UV coordinates, and particles, on the other hand, cannot be used in RealFlow without a common platform. In contrast to the RealFlow RenderKit (RFRK), the plugins support all of RealFlow's data: geometry, particles, meshes, and RealWave surfaces. The RFRK's main purpose is different, and therefore the workflow of both tools is different as well. Here is a short compilation showing the main aspects of the connectivity plugins and the RenderKit:

Meshes, on the other hand, extract their channel data from the particles, and here you can decide which attributes you want to a) include with mesh and b) finally export. This process requires a certain workflow. For more information, please read the "How to...Work with Channels in RealFlow?" and "How to... Export Meshes Correctly?" chapters..
When you work with channels you have to differentiate between vectors, reals, and integers. A RealFlow vector consists of three elements for the X, Y, and Z direction. A real number (also known as floating number) is a decimal fraction, e.g. 3.14, 745.6756, or 6.9999. Integers are numbers without decimals like 7, 433, and 264533.
