SDK3.3.0 import gltf is different from SDK3.2.4

[JhonKkk]

Hi everyone. I found that SDK3.3.0 has problems importing GLTF models, as follows, the effect of importing in SDK3.3.0:

And the effect of importing in SDK3.2.4:

This model is available here:childhood

Is this a serious problem with SDK 3.3.0? Does anyone know?

Does it load fine if you load it from code and not the SDK?

Hi, I just tested it.When the code is loaded, an error is reported as shown in the figure:

Is this a serious bug of the 3.3.2 API?

  Node scene = (Node) assetManager.loadModel(“Models/childhood/scene.gltf”);
  rootNode.attachChild(scene);
  scene.setLocalScale(0.01f);
  /* A white, spot light source. */
  DirectionalLight lamp = new DirectionalLight(new Vector3f(-1, -1, -1), ColorRGBA.White);
  rootNode.addLight(lamp);
  }

}

3.2.4 Everything is normal, 3.2.4 PBRLighting and 3.3.2 PBRLighting have some differences, I suspect this is the reason.

Can you please test if changing renderer to LWJGL_OPENGL32 will make any difference?

In main method:

LoadJ3oTest app = new LoadJ3oTest();

AppSettings settings = new AppSettings(true);
settings.setRenderer(AppSettings.LWJGL_OPENGL32);
app.setSettings(settings);
app.start();

Edit:
And by the way

How to type code blocks

Markdown code block : Embed your code in 3 backticks, like this ```<optional language> //your code here ``` If you don’t know how to type a backtick, here are some related links : How to type a backtick on windows For mac users : On qwerty keyboards it’s the key right to the left shift (along with the " key). On azerty keyboards it’s the key over the right shift (along with the £ key). This uses highlight.js, but uses a subset of the supported langages (following code block uses java)…

The same error, compile shader error, seems to refer to the GLSL code for skinning calculation.

I don’t know if my guess is correct…

[Ali_RS]

Hmm…then seems your app is somehow using an older version of JME because that error is already fixed in the below commit and should already be available in the 3.3.2-stable release.

Oh, I use SDK 3.3.0, so I use the 3.3.0 API instead of the 3.3.2 API. thanks for your hints.
