OK! this is only my second post but ill try to make it as good as possible
ok heres the basics first you will need MyWarcraftStudio 9.0 , u can find this if u google search it hopefully
Ok to begin lets say u want to make NE guy glowing eye color instead of gold to the BE green color
to do this u
1.) make a CHARACTER(make sure its caps) folder on ur desktop
2.)open MyWarcraftStudio9 and use it to open the Common.mpq file in the Data folder
3.)you find the file you want to replace the old one, in this case you go to the Bloodelf folder then Male and then it should be one of the top 3 blp's there
4.) open the NIGHTELF folder and then the MALE folder and right click the eye glow color blp and extract the treepath , open notepad and paste it there
5.)go to Extract the bloodelf glow blp and extract it to the CHARACTER folder , but make sure u have it so that when u click on the CHARACTER folder it opens up to just show a NIGHTELF(remember caps) folder and clicking on the NIGHTELF folder makes it so it shows a MALE folder and clicking on the MALE folder it shows the eyeglow blp
6.) ok! make sure u have renamed the BLP to the one of the NE guy eye glow color
7.) open MWS(well u shouldnt have closed it actualy) and then go to Pack and then click Add MPQ archive or edit MPQ archive
8.)then click Add file to MPQ archive and then go hit the "..." button and select the blp for the eye glow , but before u hit ok make sure that the words in the white box look like this CHARACTER/NIGHTELF/MALE/(input blp's name here)
9.)after this is done hit the save button close MWS and then delete all the model editing folders on the desktop
10.) run wow , and u should be all set
Note: the point is that i was trying another model editing for 2.0 guide and it was not working , and the other diffrence is that u cant open m2 files so u have to extract the whole folder, but this is a guide for poeple who have no idea wat to do in 2.0
