Welcome to the forum Sargon. Being new to Bryce, you're in for a fun-filled journey! I would agree that, jumping in and trying things out and experimenting with what Bryce can do is a great way to learn. Enjoy yourself. As for making realistic sparks in Bryce, one way would be to use a 2D pic of the type of sparks you're looking for with a transparency map. Or, someone else in the forum may know of a mat out there somewhere that would provide the results you're interested in. Off the top of my head, I'm not sure, but I'm sure someone will know. Best of luck and happy rendering!
