PyroCluster
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".
