I try to load a 3d model in jpct-ae.
I looked at all the tutorials and I think I understood, but I don't succeed to use the 3d files I have.

Indeed, I use the code that I found on this forum and which is present on tutorials for jpct. (-> http://www.jpct.net/forum2/index.php/topic,2076.msg15290/topicseen.html#msg15290)

Normally, it's working and it's without errors.

these is the code

As you see, I use one object: exquisitchair.3ds, that I have found on this site:

http://thefree3dmodels.com/stuff/furniture/exquisite_3d_chair/12-1-0-120

My problem is simple: How tu put his file in Eclipse ?

I have tried in the "res" directory, it's said error, "invalid resource directory name", I have tried without the extension, I have tried other 3dfiles, and I have tried to create a "raw directory" or an example directory and to change the path.
But the problem remains the same.

The code has nos errors, but of course I couldn't compile for the moment.

Can you help me please ?
