The other mode writes all object-related data to one single file, called “animation.sd”. This file contains all information from the nodes including their geometry and camera data. A very common workflow is to export wetmaps into separate image files, while motion and transformation data are saved within the “animation.sd”. As you can see, both methods can coexist.

With this option it is also possible to write out individual files for each object in the ABC format. Since Alembic is relatively new it is not supported by all 3D platforms so far, but for some programs there are 3rdparty plugins available. Older versions of 3D applications will most probably not be able to read this file type. RealFlow's implementation of the Alembic format supports 10 different compression levels from 0 to 9. A higher value indicates a stronger compression. As usual, the compression requires some time and so the saving process becomes slower, but it is more resource-friendly.
Arnold Scene Source (.ass)
This is the scene description format of Solid Angel's Arnold render engine. You can export simulation data to native ASS files for direct use inside Arnold.
Geometry (.obj)
The OBJ format is very common and can be read by any 3D program as well as countless plugins or helper tools. In RealFlow you also have the possibility to export OBJ files.
