a lot of the models are the same as fh2, so in some cases when we get a certain car which might be a different version of the same car (like a liberty walk edition) but we find the hood is screwed up on the new version (some models wont unpack properly) so we can take the hood from the fh2 version which is the same and stick that on the new one.. It's taking a lot of work to get these ones..
Textures... i presume you mean car skins. they are not that different to be honest, but they don't need to be either really. a car can be fully textured outside or inside quite nicely on a 2048x2048 image. in fact most games still only use either 1024x1024 or 2048x2048 textures.. theres no need to go more, the difference in filesize compared to the difference in clarity of what you would see isnt worth it.
it's not done pretty this time.. Before for FH2 we had forza studio which had a nice window for showing you the model before you exported it as a proper 3d format. Not this time. its a bunch of text files which tell batch files and dos scripts what to do. No pretty windows, just basic command prompts.
well no the game can't be modded regardless what version you have. Nobody can convert things back to the game format, we can only unpack not repack. As far as i can tell nobody is even considering looking for or trying to write a repacker. There isnt that many people working on the unpacking to be honest.
That is more or less what I'm asking. I feel that the question is relavent because the method you used to rip the models if done through game files (on the latest version of the game) might mean that the game can be modded. Don't take it the wrong way Nobby.
