It seems I have another problem to edit anything :/
I've DL all the tallstrider files (M2, skins and all the .BLP files too) and used M2MOD REDUX 4.6.1 to convert the .M2 file to a .M2i.
It's ok, it works. In the M2MOD folder, there are 3 python scripts that seems to be needed to open a .M2i file with blender (I've downloaded first the 2.76 version, but as said in the readme file, M2MOD works with blender 2.73 then I'm now using it).
I tried to open the scripts (open, navigate to the place they are, and clicked on "show script files". I tried to open the 3 scripts, no one works --'
I don't know how I can edit this .m2i, there are so much versions of each tool I can't find any solution that works alone
If somebody around here could help me to solve it, I'll be glad ^^'
I apologize to come with so much noobs questions, it's probably really easy for y'all but I feel lost right now...
Thank you for reading/helping me
EDIT : Finally, it took me around 8 hours to find where the mater was : the script files have to be paste in the blender script folder directly. And not anywhere else in the subfolders.
Now, I have to understand why M2MOD crashs when I try to convert my new .M2i in .M2.
Moder's life isn't a piece of cake, but it's so intersting... ^^
