The "NBinary Loader" could be seen as an expansion of the binary loader to combine multiple emitter sequences. This can be very important for meshing or importing particles into your 3D application, because in some programs it is only possible to import a single BIN file sequence. With RealFlow’s "NBinary Loader" different sources can be combined and exported as one emitter. With this process, meshing can be accelerated too, because settings have to made once only. Please note that it is not possible to interpolate simulations with a "NBinary Loader" or release the particles.

 

 

BIN sequences

In contrast to the binary loader, “BIN sequences” only shows a list of currently loaded files sequences. If you want to add a new series of files you have to press the “Load Bin Seq” button.

Load Bin Seq.

This button opens the file picker to load a file sequence. You can only choose one series at once. If you want to add another series of files, click on the button again, browse to the desired directory, and grab your sequence.

The number of files must be equal for each emitter. It is not possible to mix sequences with different number of files, e.g. "Circle01" carries 78 BIN files and "Square03" consists of 112 BINs. In this case, RealFlow aborts the loading process.

Remove Bin Seq.

To remove a sequence, choose it from the “BIN sequences” menu and click on this button. The name under "BIN sequences" will be replaced by “Empty” and the particles will not be visible anymore.

Mode

You can choose from: “Normal”, “Hold”, “Loop” and “PingPong”. With “Normal” the sequence simply ends with the last file. “Hold” saves the last BIN file and displays it in the viewport. With “Loop” the files sequence starts again with the very first frame. “PingPong” is a nice mode that plays the series of BINs forth and back. The last three options are only visible if the frame range of the current scene is longer than the loaded BIN file sequence.

Reverse

Choose “Yes” to play back the sequence in reverse order.

Number of files

This field shows you the number of currently loaded files.

Frame offset

If you want to shift the starting point of the sequence, enter a frame number. This attribute accepts both negative and positive values.

Reset xform

This button is used to restore the original emitter position if you have performed some relocation and want to reset it.
