SH3 Noob

[armatata]

Hi guys!

I've enjoyed sh4 so much, i decided to buy sh3. I heard the mod support for this game is amazing and I really want to try it. Since I'm not a very common subsim user, I apologize if this is not the right place for this kind of post.

First question: Am I able to activate sub interiors and full hd mod in WAC 5.0, if I am running 4gb patch?
Second question: I don't understand the activation order for WAC 5.0 and I can't find any guide. What is the installation order?

The next question is... where do i find GWX 3.0. I checked all the mediafire links, but no mod appears to be there... is there any solution to that problem?

The last question is about mods in general. I find the amount of content a bit overwhelming and don't really know where to start. Are there any other necessary mods to have, or things to know? It might also be important to say, that I got my SH3 from Steam... hope that isn't a problem with modding or anything else.

Thanks in advance!
