Fun with Particles


Hi there, Sarah here. Since we're all having so much fun with particles, I did a little digging and found a tutorial that shows how you can use the speed of a particle to determine color (or another attribute of your choosing). It's a little bit of scripting, but mostly just the runtime expression that we saw in one of the homework tutorials. There are two scary looking examples in the beginning, but the real tutorial starts after that. Look for the sentence, "So we want to create an attribute called 'speed'." Everything before that is basically background info. The tutorial itself isn't too bad to follow. The only problem is that he tends to stop in the middle of what he's doing to give you an example, and it can be a little confusing. I suggest reading through it once before you actually try and do it. There's a short movie at the end where he uses a turbulence field to create sudden speed changes. Enjoy!
