Bad news: Some problem has come with FoD. While I'm having nice progress with the background stuff, the stage has reached the limit. I guess there's a model limit or something. The case is that, even deleting textures and having a filesize lower to 2MB, I can't seem to be having the 3 modeldatas working at once. While testing, I've only managed to make it work as a whole over Battlefield, using 4 modeldatas and not 3.
This is how the stage would look now:
So, I'm not 100% sure I'm able to continue the stage, at least the way I was doing it. I have to try every possibility, changing models from a modeldata to another may work. But this will take time.
PS: These are 177 models right now.
