you didn’t apologize for help!

but it won’t work or i am to stupid.

i think there is no way like written above to duplicate the source comp in project manager and use >20 duplicated ones.

thanks everybode for helping.

@dan: if i have to duplicate every nested comp, than i do not need an expression, than i can make my keyframing directly in the comp. why would i need expression for if this simple thing wont work.

thanks, it is a good idea, but it is a workaround too and not the solution i want mostly 😉

i forgot, the nested comps are not on screen at same time.

the layer count is not the main problem.
i like the idea to change something in one comp and got the result in many hosted-comps as i wish. that’s the main idea.

the secondary problem is more the layer order, so my changing element is behind other layers, so i need theoreticaly 3 nested comps to simulate that.

is there a way to put the paramters out of the nested comp instead to put the values in.
i think about a class or an object – maybe in c#/.net – there i could write properties and every variable outside could reach this value. in the case of the comps, i walk another way, the expression “collects” the values from a fixed link.

may i write (and where to write it) thisComp.layer(index of nested comp or name).pathtrim.end = xx;?

if i unterstand right, i could give paramters from the nested to the hosting comp? how?
if it’s not right, it seemed to be a lot of work if i change something in the nested comp.

i created a new (hosting) comp, and put the nested comp in it via drag&drop from project manager.
