I use JME nightly builds. I have no such an exception.
Do you use JME beta?
@mifth, Could you tell me you used version of JME3 or the link where you download the JME3 jar package?
BTW, what is nightly builds? where can find them?
Menu: Tools → Plugins → Enable Nightly Builds. Then update your plugins. (MORE PREFERABLE WAY)
Or just download here: http://jmonkeyengine.com/nightly/
And replace your libs with nightly jars.
@mifth, I download the latest package, now another exception occurred:
[java]java.lang.UnsupportedOperationException: In material: MatDefs/LightBlow/LightBlow.j3md
The ‘FixedFunc’ technique name no longer has any special meanining.
To support fixed pipeline mode, remove that technique’s name entirely.[/java]
it seems CoreDevs removed “FixedFunc” yesterday: http://code.google.com/p/jmonkeyengine/source/detail?spec=svn9563&r=9546
Just remove “FixedFunc” as they did here: http://code.google.com/p/jmonkeyengine/source/diff?spec=svn9563&r=9546&format=side&path=/trunk/engine/src/core-data/Common/MatDefs/Light/Lighting.j3md&old_path=/trunk/engine/src/core-data/Common/MatDefs/Light/Lighting.j3md&old=9330
Or download my fixed version: http://code.google.com/p/jme-glsl-shaders/source/browse/assets/MatDefs/LightBlow/LightBlow.j3md
