Yes ,I have try the script for 2.54 on 2.55,it works fine.
But I have some question for enricocerica:
1.you have put .obj export code in this script,why don't you use import moudle? is it because you need to make some change to the export code?
2.the alpha value in .mtl file(d) is not import in octane,is that a missing function of octane?
And I notice that there are many useless message output (class ...)in console windows,maybe you can fix it in next release.
Keep on good works!
