It must be something simple but it still doesn't work. Here is my code :

// used to init a model
public void loadModel(){
   model=Loader.loadMD2(PATH+SEP+"models"+SEP+"scarlet"+SEP+"tris.md2", 0.5f);
   model.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS);
   TextureManager.getInstance().addTexture("alita2", new Texture(PATH+SEP+"models"+SEP+"scarlet"+SEP+"scarlet_dress_red.jpg"));
   model.setTexture("alita2");
   model.rotateY(5f); // not the correct angle... just to see if it works
   model.rotateMesh();
   model.build();
   model.setRotationMatrix(new Matrix());
   placeModel(model);
   theWorld.addObject(model);
    }

// used to place the model in the world (at initialization and in the game loop)
public void placeModel(Object3D model){
   SimpleVector dropDown = new SimpleVector(0,1,0);   
   Matrix rotMat = model.getRotationMatrix();
   rotMat.setIdentity();
   float distanceToGround = terrain.calcMinDistance(model.getTransformedCenter(), dropDown, 4*30);
    model.translate(0,-20,0);
   if (distanceToGround!= Object3D.COLLISION_NONE)
       distanceToGround -=10;
   dropDown.scalarMul(distanceToGround-4);
   model.translate(dropDown);
   model.rotateY(yRot);
    }



and here is a picture of the interface



My camera is well placed and follow the model when it is moving. I would like to rotate my model in order that I see its back (so I need to rotate it around the Y axis) and without interfering with axis.

I tested it with different md2 models... and all of them are looking on the right..

Do you see where my mistake is?

Thanks you
