I think it would be really useful to write one for the wiki. The same goes with both generations of ARMA.
Sorry, I'm a complete and utter n00b when it comes to texturing and modelling anything. And I can't make heads or tails of most OFP editing tutorials (except for maybe scripting). Most of them aren't even available anymore.
Frankly, I've searched absolutely everywhere for months and found nothing. How can I retexture a vehicle, if I don't even know what the original vanilla textures mean ? I wanted to just replace a roundel on a single vanilla armoured vehicle and put it into a separate addon with a custom config, but I'm not even able to do that, because there is absolutely no order or logic in what software to use, which files to open and what format to convert into another and back again.
Please, please don't point me to O2 Light or anything similar - I don't want to do any needlessly complex texturing and the utility itself never works for me, even after I repeatedly set it up precisely according to the few tutorials that exist for it. I just want to find the texture file for the roundel, swap it (manually, if I have to) and PBO back the addon (though under a different name, so it won't replace the vanilla one).
