This is my first post here so hi to everyone I have little questions that ive been trying to solve. Im relatively new to houdini and im not to sure what i can and cant do expression wise.
Basically im playing with growing objects i.e incrementing values of objects generated in a copy SOP.
So the result would be something like branches growing and spliting, or leafs growing from growing branches. Using $FF if fine if i want to grow objects from frame 1 but what i need is $FF minus the creation frameNumber of the branch, or someway to increment values starting on creation.
I have a slight feeling that i wont be able todo this with just stamping in the copy SOP. Anyhelp would be great.
Cheers
Nick

Welcome Nick!
Might be a little tricky to get exactly what you want using copy/stamp, although you can do an awful lot with it and might be able to get away with it.
However, before going down that road, what you're really describing is classic l-systems - have you looked at the l-systems SOP? I realize it means learning a new language(it's fairly straightforward), but there are some examples there, and it's exactly what you're asking for.

Yeah i kinda thought that it L-systems would be able to do this alot better. It really was more of an exercise to learn from and see what could be done with a copy sop. If i have any decent results i will post it here. It would be good to hear what others suggestions people have about my network.
Thanks for your input JColdrick

I managed to figure out a method of doing what i needed. Basically using a particle sop on my intial growing branch allowed me to use the $age variable to grow secondary branches from there creation time. Seemed to be the only way i could see doing this with out resorting to L sytems.
Jerry - Im not sure how todo what your suggesting, any tips on getting the copy time of my branches to increment from?
Cheers guys
