Are there any references for the particle modules "Trail Data" and "Ribbon Data"? I can't seem to figure them out, and getting them to even show up in Cascade is a rear-end pain. All the UDN says is:
"The Trail type data module indicates that the emitter should output trails - connecting particles to form ribbons. Trails will be discussed in a forthcoming document. "
Not particularly helpful , I'm anxious for those forthcoming documents.
