Its the price you pay for using an ancient version.
That would be even easier I guess, thank you. Would you know a noob-friendly way to do this? I tried pyModelEditor, but it doesn't like me.I also tried opening the m2 with HexEditor alas it's not as easy as it is for other files like .adt files, so I'm a bit lost. :/
Never open character models or retroported models in pymodel editor. That program will bug most of their animations.
Open your model in 010 editor and run the M2 template (viewtopic.php?f=59&t=828).Go to renderflags, look for the renderflag used by the cloack and change Alphatesting (1) for Opaque (0).
