how can I add blender for jmonkey I already downloaded jmonkey but I cant see any model therefore I downloaded blender but I cant add in jmonkey. I am using ubuntu
If you have a blender model you can simply right click them in the SDK and convert it to jME. I think that do not work if you have animation. For animation you have to export it as an Ogre model. There are articles in the wiki section, I highly suggest to read them first.
You will find some tutorials in this wiki page : http://wiki.jmonkeyengine.org/doku.php/jme3#documentation_for_intermediate_users
Also watch some tutorials about UV mapping in blender. You will use it a lot in texturing.
I do not use any of ogre or obj to import model to JME because it greatly support importing directly from blender (.blend file) .
I believe the SDK comes with blender, and this version is highly recommended to be used. Different versions require different importers for JME and I don’t think they are cross or backwards compatible.
In new release of SDK now the default blender is 2.76 which i used in those video tutorials. Even though I had no problem in previous version of SDK which was based on blender 2.75.
And I highly recommend instead of adding support for stand alone formats like FBX directly in JME just try to improve blender support.specially the material part which I described the problem for animated models in this video :
