You checked on the site right? the faq in the forum there...
What is the part your lost on , hex editing or making the save in your editor of choice or ? tell me first what part your stuck on and well go from there.
You have the dds exported?
You are modding them and have re saved them as valid dds that are the EXACT same size as the ones you extraced?
You saved them with all 9+ mip maps , of which each one you edited to show the new mods your making appear on the skin?
You are opening Bcompiler, locating your folder with your modded dds and clicking it (since there is not other working functions in bcompiler) and they are being reformatted into a file
called the same name as the one your modding but with the new ".lvl" extention?
THis in turn is the file you are opening in hex and pasting over the older version of your mod, pasting it, saving the file and playing it! (some people get lost at this point, if this is the case let me know, getting here means you at least have the idea! I will get you to the rest.
If others are having the same hex issues, post here and I can try to walk through with you all in posts....The reason faq are limited is a few of us do this differently, i personally have done so many that I have the process to a faster, more efficient method so im not searching/pasting as much but ive changed the way I do them often as more and more is learned on a daily/almost hourly basis ...this engine rocks no matter how limited some out there think it is...Kudos to LA and pand. for a real combo deal on this one
