Hi,
Thank you for your answers!

Thanks Locust for your link, i have already found it but I wanted to be sure it could help me and be the best way to do what I want to.
I said in my previous post that, at the moment, I'm doing my walking movement with a lot of frames, and I wondered if it could be a problem when exporting to Ogre XML format.

If you're going with vertex animations, your best bet is MD2. You could export all the keyframes in OBJ or 3DS, but then you'd have to manually add them to your animation in jpct. MD2 will export the whole thing in a single file.

Ok it seems to be usefull! But does MD2 only contain animation or does it also contain 3D object (like .obj and mtl)? Can I create my object3D only with MD2 or should I use .obj file and then use MD2 to animate it?

Hello,
I am working on an Android project that looks like pokemonGo. I have an avatar that I made with Blender and MakeHuman. I use the "MakeWalk" function to animate it in Blender and now I want to display this animation in my application.
I already use JPCT_AE to display my avatar on a map but I used .OBJ format and so can't animate it. I looked for solutions on the forum and website and I found three main solutions : MD2 model, Ogre Mesh format (and Bones API) and keyframe animation as it is explained here : http://www.jpct.net/wiki/index.php/Loading_3ds_Keyframes_from_Blender.

My point is : what is the best solution for my project? I want to have a 3D avatar that can be personalized by the user by changing his textures and also animate it on the map when the user is walking.
I have memory constraints so I can't use many obj files for each pose.

I need expert's advice 

Thanks a lot!
