These are never easy questions that almost never have an easy answer. I'm as active on that forum as I am on this one. If I've seen it and have an answer right you'd have one. Honestly that negativity is uncalled for, especially when everybody on those forums is working on stuff as well and it's not a huge pool of people. This particular question has been asked multiple times before, I get you'd like an answer but we are not going to stick more time into finding you a detailed answer then you did yourself through not having plowed through the forums as there is literally no guarantee our time wasn't wasted on mere curiosity. Manpower is stretched very thin there, you have no idea how much of a timedrain it is to answer every single question, especially when it's not the first time.
They are more likely to answer when the questions are specific to someone whose done research but is missing a link somewhere rather than someone asking a general question entirely and might do nothing with that information.
I already stopped looking for the answer to my second question since that one is not often or never mentioned enough for me to find the relevant threads on it. I've already looked a lot more into my first question already. It's just trying to get the .pcc files from the DLCs to load up along with the game. Finding the file(s) is easy, but applying and making the coalesce file read external data that aren't contained within the vanilla part of the game is hard. Since DLC squadmates do have their character texture as part of the vanilla game files, their squadmate "self", I guess, aren't being loaded until the game sees that you are requesting the necessary files to be loaded. I've already found a lot of relevant information on the ME3Explorer forum, just not on the thread I made. And right now, I'm trying to figure out on how I can get the coalesce file to load up Wrex's .pcc files from the Citadel DLC. There's either an easy all-around way, or I would have to do it manually, and make the files active everywhere I go within ME3.
