Hi.
I tried setting up a first demo game and it works fine. I could manage importing a single cube mesh from Blender 2.5 into jMonkey via the ogre xml exporter. And I was able to convert the xml files into .j3o, add collision detection and add some texture (unfortunately the texture chosen in Blender wasn´t used unit I explicitly assigned it in jMonkey).
Now I tried importing a complexer model a friend created. And I can create the .j3o file for the barrel mesh. But the scene can´t be converted. Everytime I try, I get an exception:

and some additional information: i crosschecked again my own import which works with the simple mesh. it is also “scene version 1.0.1” but it works. even if there are also warnings as seen below:

I dont get it. Even the ogre exporter works different everytime I try. Sometimes only the scene gets exported, other times also a cube.mesh.xml and cube.xml are getting created… ??? ;(

it seems you have to select all items in blender before chosing export, else not all meshes / materials... are being exported. at least this problem could be solved. but it would be great to hear a solution for the other problems ;(
Can you post the .material file for models that had the “Unsupported pass directive: zero” issue?
@Momoko_Fan sure, but it looks unspectacular to me:
scene.material:

}
}
}
the problem is so easy to repeat. i cant understand i am the only one facing this bug every and every over again. just open a new blender file with the default mesh → export via ogrexml → convert the mesh, then convert the scene and already it crashes and the scene cant be converted. 
i cant get my models running. is is so sad
well to me this is a bug.
Product Version: jMonkeyPlatform Alpha-4
Java: 1.6.0_23; Java HotSpot™ Server VM 19.0-b09
System: Windows 7 version 6.1 running on x86; Cp1252; de_DE (jmonkeyplatform)
in my opinion the scene importer is unfunctional. i am stopping development until we can clear this. cant do anything anyways, now. without my scene. if you need any further information, files or stuff, please let me know.

You’re using an outdated version of jME3. Download the nightly builds or update your jMonkeyPlatform to use nightly builds
@Momoko_Fan
So the result of my tests:
I completely deinstalled the SDK, deleted all files under AppData and Programm folder.
I downloaded the SDK again, and installed it
I updated the whole SDK to the latest version
I downloaded the latest nightly build of the engine.
I created a new project and removed all libs
I added the libs from the nightly build
I created a new simple template mesh in blender 2.5, selected all and exported
I compiled the mesh to j3o which always works
I tried compiling the scene to j30 and again it fails.
So it is an actual problem in the latest version. What now?

Using the nightly build that material loads fine for me
great … what about the scene file. can you see any problem here?

see last comment.
and here the actual error message when reloading the sdk. am i right that users cant even use nebeans with jmonkey? because only the sdk has the model importer / converter? how could i get models into the normal netbeans version? and is there already a release plan for the next alpha or maybe beta version of the sdk? thanks for the patience… i´m quite frustrated but i hope you can get this thing running anyways.

ok i finally managed to get it running. SDK → Tools → Plugins → Settings → activate “nightly” ----> gold worth
downloading the trunk of the sdk didnt help but activating these settings in the normal ide works fine as it seems.
thanks for the patience.
You can use NetBeans/Eclipse with jME. The importers are all there so you can actually load .scene and .mesh.xml files directly
