I made a new project and used the java source from TestBumpModel.java. I compiled and ran it successfully on mac and android. I then replaced the two lines
Spatial signpost = (Spatial) assetManager.loadAsset(new OgreMeshKey(“Models/Sign Post/Sign Post.mesh.xml”));
signpost.setMaterial( (Material) assetManager.loadMaterial(“Models/Sign Post/Sign Post.j3m”));
with the line
Spatial signpost = assetManager.loadModel(“Models/test/plane2.j3o”);
plane2.j3o is a simple plane made in Sketchup, exported as obj format model and then converted to j3o using the sdk.
The program runs as expected on mac but gives ‘cannot render mesh without shader bound’ on the android.
What is that error and how do I get rid of it?

Check the log higher up, there’s probably an error with some shader
Here is a snippet from the ddms log. I see errors in there but I have no idea what the significance in.

Looks like some shader is hitting the varying limit, probably Lighting. Make sure you’re using the jME3 SVN build since the nightly is from August and is outdated at this point
Could you clarify about what I should get from the svn nightly and where I should put it. I’m kinda new to a lot of the jme stuff.

What he said only applies when you are not using the jMonkeyEngine SDK to deploy to android. If you are using for example eclipse, refer to the documentation on getting jME3 from svn.
I am using the jme SDK to deploy directly to the phone.
