Sorry for reviving this thread. Why the SDK needs different drivers then the engine itself? Running any jME app works like a charm but the SDK scene editor doesn’t.
Anyway, from my experience, if you have topic issue and if you use Linux, it mean you didnt install all driver components or something messed with drivers.
Still, just to mention, SDK is not “required” to use JME(you just need gradle/ant). But its a nice optional tool to use.
