Any suggestions?

Edit: I also find that it isn't appears with the swbf viewer.

Edit2: * when I try to edit the msh file it says : cannot open file "(msh file location in the world folder)"for write access.

Please I'm stuck, I need help, it's an important object for my map and  that is now a cuple of day that I don't find the solution,....

For the read only problem, what folder are your ODFs in?  It could be a permission issue on the folder location.

It's in my world's odf folder,

(and I recently use notepadd ++ for editing, is that can be the problem eventually ?)

Edit: I almost forgot to tell you that I have already change the original TGA from the original Object (not from the assets, but from my world folder; but I only remplace the TGA by keeping the same name,and of course It works perfectly ,unfortunetly  the other copies no,...
