Hi there !
when importing a gITF model from blender , i get this error in JME SDK , it seems that something goes wrong with triangulating faces of the mesh , inspite of i am already triangulated all faces in blender .
My Mesh :
How did you determine that? I didn’t see anything about it in the output.
JME won’t do any triangulating.

well, message is simple, but reason not.
Maybe your gltf were linking texture from some external location. Or maybe you incorrectly use importer.
Myself, when using SDK, i did not use Importer, just copy gltf into project and convert to j3o when needed.

Because the same problem happened with me before , & my solution was to evaluate a triangulated fan face rather than a Ngon Face for the mesh in blender after generating a cylinder & jme imported that successfully , now I am doing the samething plus selecting all faces & triangulating them after modelling & it does not work 
@oxplay2 i have created the mesh normally in blender with no texturing …just modelling ,
Yes , me too but the same problem exist the importer & copying the object are the same but I have given the importer a try to see if I can see the object in the overview plate or not , and I am not seeing it plus jme Editor cannot render it
I know that nothing goes wrong with jme j3o binary converter , but there’s something that’s done wrongly everytime I export from blender & import into jme
If you use something like JMEC to convert it to j3o from the command line then maybe it will give more information. I kind of doubt it but it might be worth a try.

@pspeed I will try that one & tell you if it works , thank you 
I don’t know if it will work any better since it’s using the same basic JME code (though there is always the chance)… but sometimes the SDK swallows useful error information. So there’s maybe a 20% chance that JMEC may provide better error information.
Edit: but for example, if there is an exception then we will see the stack trace 100%.

About SDK swallows errors , yes i agree
@oxplay2 found that when copying & converting to j3o format & it rarely appears
EDIT : i was doing just a trial to be sure & found that

- The SDK will triangulate models only if you directly try to load a blend file, other export formats such as gltf will do the triangulation during export.
- I think this message is mostly a warning. The core problem here is that the SDK’s AssetManager can only load assets from inside the project directory (like a real asset manager, too), and thus it copied the gltf in, but since the “original model” is out of path (i.e. inside of Blender Projects), it will only watch for changes on the copied file.
So the warning basically only says: Caution, typical reapplication will not work, you need to copy the file.
The other problem you ran into is fixed with a more recent jme version, so might try the 3.3 beta SDK release. It’s because you probably run mesa, which is strict on OpenGL 2.1 instead of allowing more (typically drivers allow even strange mixtures from 2.1 up until 4.4 (or whatever your card supports)).
You may want to look into it, I don’t know if you can change that, because otherwise you need to enforce a core profile for a specific version.
This was the commit solving that btw

I noticed this part in the Issue title but I cannot understand why is that happens when I tried copying the file also , creating a new project also displays the same error
I am using SDK 3.3.0 beta1 SNAPSHOT , may be that was the problem !?
Because the gltf file was in your blender projects folder at the time of the conversion, but I don’t think this is a problem. It just copied it.
And yes, only v3.3.2-stable-sdkpreview1 has the fix so far, unfortunately. But then jme/the SDK is still running on OpenGL 2.1 only mode.
