I use actually prc 3.2, cep 2.1 and acp 3.0.
But i was wondering about the 4.0 and i've tried to put the acp 4.0 hak right under the prc haks and it works. If is under i think that if the Acp works, then the prc should not have problem, is it right?
About cep, someone has an idea of what kind of file are in danger of creating conflicts?
I use ONLY cep core haks, cause the phenotypes have conflicts with cep, so my opinion is that also the cep should not have problems with acp 4.0
I will test all the acp animations(i've tried just 2 on 11 for now)
If all works, i think acp and prc don't have problems
About cep i will post on their forums my question too, and i will test something about cep.
