Houdini Indie and Apprentice » rand() help

Hi, this should be easy for most of you out there. I am using geometry to scatter popcorn kernels (I have 3) around a model of a “pile.” Anyway, I figured out how to use the scatter SOP and copy SOP to aid me in this, and also Im aware of the “switch” SOP to switch between the 3 kernels. Where I need help is: I am assuming I need to throw in the rand() expression into the input of the Switch node to vary the popcorn kernels all over the model. rand($F) will not work because this is just going to be a stationary pile of popcorn. What do I put inside of the parentheses to get that randomization? Or am I needing to throw in another node somewhere? I feel like this should be really easy. Thanks!

I was following along the tutorial for blowing away an image. When doing the animation, it really taxes my system. Like, it is unbearably slow. My computer is running 64 bit Windows 7, Nvidia 512 dedicated, AMD quad core so i really didnt think there would be any issues. I am just hoping I missed some setting in Houdini. When I go into “popnet1” and run the simulation without the color information from my image, it runs just fine. But when I go outside that node and run the animation in the particle emitter level, it acts like its doing something really hard. At a birth rate of just 100, it takes about 10 seconds to go through each frame. On top of that, When I go back to frame 1, it doesnt cache the frames at all, it starts all over! Am i doomed? Should I have sprung for a faster card? Thanks for the help.
