Yes, you’re right. Here is my short tutorial. Feel free to use, edit and add it to the tutorials section as desired.
3ds Max Bone Animation to JME3 using OgreMax plugin
For this tutorial I used 3D Studio Max 2012 and OgreMax 2.4.3 free edition
==Create Model and Bones==
-Create a new file
-Select the “Create” tab > “Geometry” > “Cylinder”
-Draw a cylinder, lets say with 8 height segments (must be enough for a smooth deformation)
-Also check “Generate Mapping Coords.”
-Click “Create” tab > “Systems” > “Bones”
-Add some bones in the center of the cylinder
-Select the cylinder, right click it and click “Convert To:” > “Convert to Editable Mesh” to prevent issues with OgreMax
-Click the “Modify” tab > “Modifier List” and add the “Skin” modifier
-Beneath “Bones:” click “Add” and select all of your bones
-You may also edit the envelopes, but for a small test the default settings are ok
==Create the animation==
-Select the cylinder, and click “Display” tab > “Freeze Selected” so it is easier to select the bones during animation
-Select the two top bones and enable the “Auto Key” mode
-The first key frame will be created automatically. Move the animation track slider to frame 5
-Move the selected bones a bit. The cylinder mesh will be deformed. Because you are in the "Auto
Key" mode, a key frame will be created
-Create some additional key frames. You may also select more bones and move or rotate them
I’ve created 25 frames and the last key frame equals the first, so the animation is loopable
-After creating the animation, disable the “Auto Key” mode
==OgreMax settings==
-Open the “OgreMax Scene Settings” dialogue from the menu
-In the “Meshes” tab, enable “Export XML Files” and disable “Export Binary Files” as well as
“Export Vertex Colors”
-Click the “Environment” tab and uncheck “Export Environment Settings”. Otherwise the JME importer will throw a NullPointerException
-If you have textured your model, you may also check “Copy Bitmaps to Export Directory” in the
“Bitmaps” tab
-Unfreeze the cylinder by clicking “Display” tab > “Unfreeze All” and select it
-While having the cylinder selected, open the “OgreMax Object Settings” dialogue from the menu
-Open the “Mesh Animations” tab and select type “Skeleton”, “Export Skeleton” : “Yes”
-Below “Mesh Animations” hit the “Add…” button
-Assign a name to the track, maybe “wobble”. The track type must be "Skin. Set the right "Start/End
Frames" for your animation
-Hit ok and you will see the animation in the table. You may add additional animations by selecting other frame ranges, if desired
==Export and Import==
-When all animations are in the list, select “OgreMax” > “Export” > “Export Scene” and name the file “worm.scene”
-Create a JME test class that imports the file, get the animation controller and start the “wobble” animation

You will see your worms strange movements. Have fun!
