Particles cache -Alembic- (.abc)
Alembic files for grid domains support multiple channels from which you can choose when you expand the “Particle cache (a.bc) branch. In contrast to standard SPH fluids, the particles from grid fluids only carry some magnitudes: position, velocity, texture, vorticity, normal, and id. 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.
Particles cache -Arnold- (.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.
Particles (.pxy)
“PXY” is an internal format that can be used with RealFlow and the RealFlow RenderKit. PXY is a proxy format and only stores a particle’s Id, position and velocity. Depending on the adjusted quality level under “Options”, some particles are left out during storage, but it is perfectly suited for high volumes of particles. There are five quality levels (best – draft) to choose from. They can be seen/adjusted with a double-click on the “Best” option right of the export resource's name.
