I've just started working with jMonkey, and am currently working through the tutorials.
However, I just got to the part where .j3o files are explained, and why this is neccesary. The following to-do list is given:
Open your JME3 Project in the jMonkeyEngine SDK.
1. Right-click a .Blend, .OBJ, or .mesh.xml file in the Projects window, and choose “convert to JME3 binary.
2. The .j3o file appears next to the .mesh.xml file and has the same name.
3. Update all your loadModel() lines accordingly.
I wanted to try this out, and so I tried to convert the Ninja.mesh.xml file (project HelloAssetTutorial -> Libraries -> jme3-test-data -> Models.Ninja -> Ninja.mesh.xml). However, when I right-click this file, only a box appears to 'Open javadoc' (which is unclickable).
I checked the plug-ins, and OgreXML Tools is activated. Do I need to download something else or am I missing something?
Thanks in advance!!
