Convert the RealFlow | Cinema 4D particles into Thinking Particles:

• Open Simulate > Thinking Particles > Thinking Particles Settings... or inside your Fluid node click on Particles > Thinking Particles Settings... 

• Right click on the "All" branch and choose "Add" to create a new group.
• We recommend changing the default name ("Group.1") to something more meaningful like the fluid container's name.

The new group has to be linked to the according fluid container:

• Drag the group to the fluid container's Particles > Thinking Particles field.

• The group can also be connected to MoGraph nodes, a "Particle Geometry" object, etc.

The connection to PyroCluster can be established with a few clicks:

• Create a "Particle Geometry" object (Simulation > Thinking Particles)
• Open Simulate > Thinking Particles > Thinking Particles Settings... and look for the "Fluid" group you want to use with PyroCluster.

• Drag the "Fluid" group to Particle Geometry > Particle Group
• Apply a "PyroCluster" shader to the "Particle Geometry" object.
• Add an "Environment" object and attach the "PyroCluster - Volume Shader".
