Code: [Select]

try{
                    model = Object3D.mergeAll( Loader.loadOBJ(getResources().getAssets().open("Katarina_Pirate_object.obj"),getResources().getAssets().open("Katarina_Pirate_material.mtl"),10));
                }catch (Exception e){
                    Log.e(TAG,e.getMessage());
                }
                model.setTexture("katarina_pirate_diffuse.png"); // it's the name of the texture in the TextureManager

Maybe the model has no texture coordinates?

the  coordinates were given in the mtl file? or in the obj file? wherever, i tried with another obj model and i have the same problem

In the obj file. The mtl only defines the texture names and such.

Yes, the file obj has the coordinates of the texture, could be a problem whit the lights? or i must add another line of code?

Just for the record for load the texture, i put the attribute of material on null and then i followed the tutorial of the wiki

Code: [Select]

try{
                    skin= new Texture(getResources().getAssets().open("Katarina_pirate_diffuse.png"));
                    model = Object3D.mergeAll( Loader.loadOBJ(getResources().getAssets().open("Katarina_Pirate_object.obj"),null,10));
                }catch (Exception e){
                    Log.e(TAG,e.getMessage());
                }

                TextureManager.getInstance().addTexture("Katarina_pirate_diffuse",skin);
                model.setTexture("katarina_pirate_diffuse.png");
                model.build();
                world.addObject(model);
