Is there a way to mark a LightProbe as "visible" in game

General Discussion
1

I have a procedurally generated terrain and I’m using PBR. I currently am setting the probes position to Vector3f(terrain.localTranslation.x / 2, 50f, terrain.localTranslation.z / 2). This should place the probe in the center of the terrain but it would be nice to somehow be able to somehow see it just to verify. I didnt see any functions that looked like it may achieve this task. Something similar to bulletAppState.isDebugEnabled.

So far I have found this Debugging :: jMonkeyEngine Docs. I implemented the SceneProcessor but the screen is all black. I had to hack a couple things to get the game to not crash.

class WireProcessor(assetManager: AssetManager) : SceneProcessor {
    var renderManager: RenderManager? = null
    var wireMaterial: Material = Material(assetManager, "/Common/MatDefs/Misc/Unshaded.j3md")

    init {
        wireMaterial.setColor("Color", ColorRGBA.Blue)
        wireMaterial.additionalRenderState.isWireframe = true
    }

    override fun initialize(rm: RenderManager, vp: ViewPort) {
        renderManager = rm
    }

    override fun reshape(vp: ViewPort, w: Int, h: Int) {
        println("reshape")
    }

    override fun isInitialized(): Boolean {
        println("initialize $renderManager")
        return renderManager != null
    }

    override fun preFrame(tpf: Float) {
        println("preFrame")
    }

    override fun postQueue(rq: RenderQueue) {
        println("postQueue $renderManager")
        renderManager?.setForcedMaterial(wireMaterial)
    }

    override fun postFrame(out: FrameBuffer) {
        println("postFrame $renderManager")
        renderManager?.setForcedMaterial(null)
    }

    override fun cleanup() {
        println("cleanup $renderManager")
        renderManager?.setForcedMaterial(null)
    }

    override fun setProfiler(profiler: AppProfiler?) {

    }
}

This is how I implemented it

val p = WireProcessor(assetManager)
        viewPort.outputFrameBuffer = FrameBuffer(10, 10, 10)
        viewPort.outputFrameBuffer.addColorTarget(FrameBuffer.FrameBufferTarget.newTarget(rock))
        p.initialize(renderManager, viewPort)
        getViewPort().addProcessor(p)

I think you can use

LightsDebugState debugState = new LightsDebugState();
stateManager.attach(debugState);

Thanks I will play around with it. I can see the DirectionalLight that I added to the scene. Found a but where if the player points the mouse up he can just walk up into the sky, even with gravity set. Trying to get that figured out then I will be coming back.

This is definitely what I was looking for thanks.
