Problems Exporting Animation from 3dMax using Ofusion

I am trying to export animation from 3dMax using Ofusion into ogre.
The .osm file that I got has the xml tags for the animations:

<entity name="Cylinder01" hidden="false" filename="Cylinder01.mesh" CastShadows="yes" ReceiveShadows="yes">

            <position x="341.24374" y="167.05254" z="-70.647644" />

            <rotation x="-0.70710677" y="0" z="-0" w="-0.70710677" />

            <scale x="1" y="1" z="1" />

            <animations>

                <animation name="Test" loop="true" length="3.33333">

                    <keyframe time="0">

                        <position x="341.244" y="167.053" z="-70.6476" />

                        <rotation w="-0.707107" x="-0.707107" y="-0" z="0" />

                        <scale x="1" y="1" z="1" />

                    </keyframe>

                    <keyframe time="0.0333333">

                        <position x="341.026" y="167.053" z="-70.6476" />

                        <rotation w="-0.707107" x="-0.707107" y="-0" z="0" />

                        <scale x="1" y="1" z="1" />

                    </keyframe>

......

but the problem is when I am loading the scene the mesh with the animation is not moving.
Below is the code I am using to get the scene:

OSMScene oScene;

oScene.initialise("pyramidAni1.osm", NULL);

oScene.createScene();

mSceneMgr = oScene.getSceneManager();

mCamera = mSceneMgr->createCamera("PlayerCam");

mCamera->setPosition(Vector3(0,0,500));

mCamera->lookAt(Vector3(0,0,-300));

mCamera->setNearClipDistance(5);

Viewport* vp = mWindow->addViewport(mCamera);

vp->setBackgroundColour(ColourValue(0,0,0));

mCamera->setAspectRatio(Real(vp->getActualWidth())

Are there any extra configurations I need to do? what may be the problem?

I'm not a coder. but I don't think node animation is a Ogre native feature but an Ofusion one. That's why it's handled inside the OSM file. Using it in code is slightly different in Ogre and has to be updated a certain way each frame. There have been a couple of threads in the forum that cover using node animation. I don't recall which off the top of my head.

Use the search feature, there are several threads with sample code that shows how to animate your scene, or see the oScene Loader demo application code, it contains the animation code you need, in the frame listener part

better check the examples yourself, especially since there is a difference between different type of animations,
but this code should do what you're after:

on load scene



if (mSceneMgr->hasAnimationState("Test")) {

Ogre::AnimationState *sceneAnimState = mSceneMgr->getAnimationState("Test");

sceneAnimState->setEnable(true);

}

on frame update



float speed = 1.0f;

if (mSceneMgr->hasAnimationState("Test")) {

Ogre::AnimationState *sceneAnimState = mSceneMgr->getAnimationState("Test");

sceneAnimState->addTime( evt.timeSinceLastFrame * speed );

}
