Very importantly, this is not a cache system.
Put simply, the xpDataImporter reads data from a source file and uses that data to create new particles.
To exchange data with other applications, the data needs to be in a common format understood by many different applications.
X-Particles imports and exports data in comma-separated value (CSV) format.
This is a simple text file in which individual items of data are separated by a comma or other delimiting character.
As such, it can be saved or loaded (and edited) by anything from simple text editors to spreadsheets, databases and a wide range of other applications such as After Effects.
xpDataImporter, Object tab menu settings.
Drag an emitter into this field.
This is the emitter which will be used to create the new particles.
