Making multiple versions of a render
I’ve posted this problem a while ago, but got no responses. Hopefully somebody more versed in scripting than myself has a solution…
I have an slider control in my comp, that when changed will affect the content of the comp itself. There will be 336 versions of this comp to be made. Is there a way to either automatically create 336 different renders, each with the variable incremented by 1? Or, is there a way to automatically make 335 copies of this comp, again with the variable being incremented by 1?
It seems daunting to do this all manually – If anyone has any ideas, I would greatly appreciate them!

If you named your first comp something like this:
myComp_1
and add an expression like this to your slider:
s = thisComp.name.split(“_”);
offset = 0 + s[s.length-1] – 1;
value + offsetthen duplicate the comp in the project bin, the slider in each successive comp (myComp_2, etc.) will be incremented by one.
Hope that’s what you were after. You could also do it with a script, but this is probably easier.

That looks like it’s exactly what I need. Thanks Dan!

Hm. I thought that would fix it, but I failed to mention that I have nested comps creating data based on that variable in “Main_1”. So even though Main_2 has that one variable changed, the nested comps are still pulling values off information from Main_1…

I’m not entirely sure this relevant to your situation, but it’s importatnt to know that you can’t have a precomp behave differently depending on which comp it’s nested in.

Then is there no way to do this?

Well, you could duplicate all the comps in the chain and give them unique names. If you’re clever with your naming scheme, you can have your expressions find the parent comps based on the name of the comp that the expression is in. For example, expressions in SubComp_5 would look for values in ParentComp_5. I’m not sure if that helps your situation or not.
