Hello everyone, PBRLighting cannot be optimized using InstancedNode and has reported an error. I can’t find a solution
The code is as follows:
public class TestPBRSimple extends SimpleApplication {
private boolean REALTIME_BAKING = false;
public static void main(String[] args) {
new TestPBRSimple().start();
}
@Override
public void simpleInitApp() {
InstancedNode inst = new InstancedNode("inst");
rootNode.attachChild(inst);
Geometry model = (Geometry) assetManager.loadModel("Models/Tank/tank.j3o");
MikktspaceTangentGenerator.generate(model);
Material pbrMat = assetManager.loadMaterial("Models/Tank/tank.j3m");
pbrMat.setBoolean("UseInstancing", true);
model.setMaterial(pbrMat);
inst.attachChild(model);
inst.instance();
ChaseCamera chaseCam = new ChaseCamera(cam, model, inputManager);
chaseCam.setDragToRotate(true);
chaseCam.setMinVerticalRotation(-FastMath.HALF_PI);
chaseCam.setMaxDistance(1000);
chaseCam.setSmoothMotion(true);
chaseCam.setRotationSensitivity(10);
chaseCam.setZoomSensitivity(5);
flyCam.setEnabled(false);
Spatial sky = SkyFactory.createSky(assetManager, "Textures/Sky/Path.hdr", SkyFactory.EnvMapType.EquirectMap);
rootNode.attachChild(sky);
// Create baker control
EnvironmentProbeControl envProbe=new EnvironmentProbeControl(assetManager,256);
rootNode.addControl(envProbe);
// Tag the sky, only the tagged spatials will be rendered in the env map
envProbe.tag(sky);
}
float lastBake = 0;
@Override
public void simpleUpdate(float tpf) {
if (REALTIME_BAKING) {
lastBake += tpf;
if (lastBake > 1.4f) {
rootNode.getControl(EnvironmentProbeControl.class).rebake();
lastBake = 0;
}
}
}
}
