RasterMind Brad Nesseth posts another tutorial for Cinema 4D creating PyroCluster Fire on Text, however he notes that this technique can be used anywhere. Check out the tutorial for Creating PyroCluster Fire Text with Cinema 4D at RasterMind.
From Brad Nesseth who speaks about his tutorial: “In this tutorial I go over how to use the preset – TP Surface Emitter, using the PyroCluster. I used this technique on text, but the technique will apply to using thinking particles to emit from any polygonal object. I also touch on using groups for your different particle systems.”
