Another simple preset is now on Red Giant People for your Trapcode Particular needs. Use with the text, or without it. The download .zip gives you the AE project, the preset, and images files. If using the preset in another project, just place the “leaf.jpg” in a 50×50 comp, and use that as your particle texture in Particular. The colors of the leaves are customizable, as well as size, gravity, rotation speed, etc.
PS. I figured out which font RGP uses for their logo. “Century Gothic,” I think.
