AE doesn't care whether a bunch of PSD layers is from one file or multiple ones. You have to replace them manually. This is simply a limitation of the process and the file format. Of course there could be scripts out there that facilitate the process in some way...
to help with the many composisions i also made many PSD files with each individual Body part
this is not a good idea to have different PSD for every part. the whole point of working in layers is that you can have a mulit-layered file and import it to Ae with having the different layers as separate layers (because you import it as a composition). if you are making different characters then making a different psd for each is probably a good idea.
So the main file that i created to house everything doesnt wanna be replaced
if you changed the file name on any mulit-layered PSD file, you will need to manually replace each layer or try and use a script. try this script and see if it solves your problem: Batch Search-n-Replace Paths - aescripts + aeplugins - aescripts.com
here's a thread with a similar issue but he had to just replace the name of an already imported mulit-layered psd file with a description of the process: Re: Reconnecting a renamed PSD
maybe manually is the only way to go here, but hey - you learned a valuable lesson!
Thanks alot for that!
really helpfull and nice reading your reply learnt alot from it,
But as its with most things another problem has come up
For reasons I dont quite understand, the files that are replaced
are being moved around for no reason, (as in the posission of the layer is being thrown about) the key frames all stay intact and the movement is mostly fine (apart from the puppet pins which for some reason half have detached and are moving nothing and the other half are working fine but moving the layer in the wrong place)
This has happened to all the footage I replaced from the Master PSD file.
So it the problem in the fact that i am taking these from a new PSD file (its the same one as before but compact, same size, same files, just different name, and added layers)
or is it after effects's problem
As in if replaced them in the wrong way which i dont think so (Just incase though (clicks on missing layer replace footage-> clicks PSD->choose layer->Merge layer styles into Footage (i did try ignore layer styles and did nothing different ) and then lastly document size.
Is there a way to fix this or do i have to manualy go throught layer layer and move them to the right place, and what about the puppet pins?)
Thank you so much dude
Your such a life saver
I feel like an idiot for not thinking about that but man you saved my life.
Have a lovely Christmas!
Great! we learn all the time and we're only idiots if we think we know everything there is to know.
