- Attach the fluid container(s) or Thinking Particle group(s) to the meshes node's "Links" or "TP Group" fields.
- "Resolution" provides five levels of detail. "Medium" and "Medium-High" offer a good balance between meshing speed and the final number of polygons.
- In order to create mesh the engine creates spheres around the particles and blends them. The size of these spheres is defined through "Radius". The value depends on the number of particles.
- "Smooth" helps to remove removes unwanted structures from the mesh and blends the polygons. Values between 3 and 8 give satisfying results in most cases.
- If the mesh appears "blobby" and thick increase "Thinning". This will shrink the mesh and fits it to the underlying particle cloud.
- "Relax" and "Relax Iterations" help to sharpen the mesh's borders. Try to avoid very sharp borders, because they look unnatural.
- "Auto Mesh Normals" helps to get a smoother impression of the mesh in the render, but Cinema 4D's "Phong" tag will no longer affect the mesh.
Test Meshes and Caching
You normally create several test meshes with different parameter combinations before the entire simulation range is being meshed:
...
If you want to mesh the entire simulation the particle part has to be cached first. Then go to Scene > Cache and press "Cache Meshes". RealFlow | Cinema 4D will read the particle files and create the meshes under the "Cache Folder".The meshes can be shaded and rendered
