KHR_Transform

artlake · March 1, 2023, 6:42am

I build the model and set material to it following this shader docs
https://learn.foundry.com/modo/content/help/pages/shading_lighting/shader_items/gltf.html

everything worked smoothly and in modo was no warnings (if material has problems modo shows warning on export), I also checked the model in gestaltor, windows 3d viewer, and blender it is as expected. but in jme no material only a white object and i get following warning

NOTE: I Used adobe substance to create texture maps from a photo, ao,roughness, and metalic produced grayscale, so i changed profiles to srgb in photoshop then i used this tutorial Combine Maps into RGB texture (Better) - YouTube to combine them into one rgb clip as modo needs it, i also used normal multiply blend mode for transparent amount(alpha) in modo.
this is a state i used to attach the model “frisebee” to the scene.

@Override
    protected void onEnable() {

        app = (SimpleApplication) getApplication();
        rootNode = app.getRootNode();

        frisebee = getApplication().getAssetManager().loadModel("Models/freezbeez/gagafrise.glb");
        Node probeNode = (Node) getApplication().getAssetManager().loadModel("Scenes/defaultProbe.j3o");
        LightProbe probe = (LightProbe) probeNode.getLocalLightList().iterator().next();
        rootNode.addLight(probe);


        rootNode.attachChild(frisebee);

        CameraControl cameraControl = new CameraControl(
                getApplication().getCamera(),getApplication().getInputManager());

        cameraControl.setSpatial(frisebee);
        cameraControl.setControlDir(CameraControl.ControlDirection.SpatialToCamera);
        frisebee.addControl(cameraControl);


        Spatial torus = getApplication().getAssetManager().loadModel("Models/torus/untitled.glb");
        torus.setLocalRotation(new Quaternion().fromAngleAxis(FastMath.QUARTER_PI,Vector3f.UNIT_Y));

        rootNode.attachChild(torus);

        getApplication().getViewPort().setBackgroundColor(ColorRGBA.DarkGray);
        dl = new DirectionalLight();
        dl.setDirection(new Vector3f(-1, -1, -1).normalizeLocal());
        rootNode.addLight(dl);
        dl.setColor(ColorRGBA.White);
        getApplication().getStateManager().getState(BulletAppState.class).setDebugEnabled(true);




        Spatial sky = SkyFactory.createSky(app.getAssetManager(), "Textures/Sky/4kresovled.hdr", SkyFactory.EnvMapType.EquirectMap);
        rootNode.attachChild(sky);
    }

KHR_texture_transform is added in JME 3.6. Try with JME 3.6.0-beta2.

artlake · March 1, 2023, 8:57am

thank you

artlake · March 1, 2023, 9:09am

can you please give me the link to the implemention of the khr_transform in jme source github?

I just test it with the new beta version still the same result!

this is the only warning i get

I just changed jmonkeyengineVersion in game, app, desktop gradle build files
this is the full log i get

See, for the above warning

artlake · March 1, 2023, 9:38am

well what about unchanged result of the 3d model whit no warning how i debug it now?

Ali_RS · March 1, 2023, 9:41am

Can you upload the model so I can try it?

artlake · March 1, 2023, 9:43am

i just tried it with libgdx importer it working as expected!

yes i can upload wait please i will send the link in private message to you
EDIT: i sent it here

artlake · March 1, 2023, 9:50am

here is the link please use it

Ali_RS · March 1, 2023, 9:51am

I do not understand this. Do you mean you can view the model fine in LibGdx but not in JME?

artlake · March 1, 2023, 9:57am

no bro don’t get me wrong, i thought since that is in java maybe be helpful. I like both jme and libgdx i have several 2d games done in libgdx many times i inspired by codes there.

and yes it is fine in libgdx if it is helpful to you

Ali_RS · March 1, 2023, 10:02am

I see, I will try it and let you know the result.

Ali_RS · March 1, 2023, 10:33am

It loads fine for me

Tried in TestGltfLoading

and replaced

with

loadModel("Models/gagafrise.glb", new Vector3f(0, 0, 0), 1);

artlake · March 1, 2023, 10:43am

I don’t get what makes the this code diffrent with my code,
so for loading glb files, Spatial s = assetManager.loadModel(“model”);
is not enough? i think i need to have GltfModelKey too right?
would you please retest in like you just made a new project in one class extends simpleapplication and with just minimum essentials?

Ali_RS · March 1, 2023, 11:03am

I think you need to add a lighprobe to your scene.

Searching for “how to add a lightprobe” in the forum you will get a plenty of result I belive.

artlake · March 1, 2023, 11:05am

artlake:

Node probeNode = (Node) getApplication().getAssetManager().loadModel("Scenes/defaultProbe.j3o");
        LightProbe probe = (LightProbe) probeNode.getLocalLightList().iterator().next();
        rootNode.addLight(probe);

I already have it, I mean it doesn’t work with light probe @Ali_RS

Ali_RS · March 1, 2023, 11:11am

Hmm, then I do not know what is the issue. You may need to create a minimal test case so we can try it.

artlake · March 2, 2023, 1:56pm

hey @Ali_RS today i found out with this code

        FilterPostProcessor fpp = new FilterPostProcessor(assetManager);
        int numSamples = context.getSettings().getSamples();
        if (numSamples > 0) {
            fpp.setNumSamples(numSamples);
        }

//        fpp.addFilter(new FXAAFilter());
        fpp.addFilter(new ToneMapFilter(Vector3f.UNIT_XYZ.mult(4.0f)));
//        fpp.addFilter(new SSAOFilter(0.5f, 3, 0.2f, 0.2f));
        viewPort.addProcessor(fpp);

material of the frisebee get semi visible (not fully as expected) also i tried to subtract alpha in modo, and also to make transparent amount opacity to 0 but nothing took affect except that filter but also game get lots of lags. despite the fps keep at 60 still lags.

artlake · March 2, 2023, 2:31pm

I also may find something even more interesting, i used babylon.js to inspect the model, i found if i choose to display vertex colors i get something similar to jme, so how can i check to see if the model has vertexcolors true or false in jme? I cannot cast spatial to geo i get cast exception in jme as unamed module

pspeed · March 2, 2023, 3:20pm

doubts.

Please never ever ever mention an exception without the stack trace. Completely useless. Like “I did it and got an error”. That’s nice.

But anyway, 99.99999999% of models loaded will be a Node… which will have Geometry underneath them that you can trivially find with a scene graph visitor.

Edit: added bold on the part that I doubt.
