Current as of July 31, 2013.
Howdy folks. Just a heads up if you are using the newest version of the ME3Explorer, there is a bug which breaks the ability to use both mesh mods and texture mods at the same time. If you try both you will likely get black texture bugs and errors.
Official bug report thread.
If you are using Texmod as your current method of texture replacement, you have nothing to worry about!
I will update again if I learn otherwise.
Update 08.04.2013: SVN 473 should be fixed.
A detailed explanation from Ottemis on the current state of ME3Explorer. This is relevant to both mesh and texture mods, users and modders alike!
