jgltf-browser preview release 4 is not support glTF 1.1?

It seems that it becomes an error when reading the following sample. https://cdn.rawgit.com/javagl/gltfTutorialModels/master/SimpleTexture/glTF/SimpleTexture.gltf

Errors (1)
  Message: The value is null when looking up key [exampleTexture]
  Context: glTF -> scenes[scene0] -> nodes[node0] -> meshes[mesh0] -> meshPrimitives[0] -> materials[textureMaterial] -> techniques[textureTechnique] -> uniform u_diffuse -> technique.parameters[diffuseParameter] -> textures[[exampleTexture]]
Warnings (1)
  Message: The value of techniqueParameters diffuseParameter is ArrayList, but should be String

I want latest gltf-browser jar…

@cx20 The point about the texture being displayed upside down that you mentioned in https://github.com/javagl/JglTF/issues/10#issuecomment-269795305 has been “fixed”. Actually, there was nothing wrong. But it was considered to be potentially confusing in https://github.com/AnalyticalGraphicsInc/cesium/pull/4808#issuecomment-275660392 :

Originally, the texture coordinates had been a “unit square”

0,1---1,1
 |     |
 |     |
0,0---1,0

And now ( https://github.com/javagl/gltfTutorialModels/commit/3a2dbf403a25021e3156ba0390f4e8ee2a603d18 ) they are a vertically flipped unit square:

0,0---1,0
 |     |
 |     |
0,1---1,1

I have also updated the texture image to reflect this, and emphasized this in the README at https://github.com/javagl/gltfTutorialModels/tree/master/SimpleTexture .

Maybe it will help to reduce the confusion. Of course, this is not a reliable analysis, but searching GitHub for issues involving texture AND (flipped OR "upside down") at least gives a rough idea about how many hundreds of thousands of work hours have been wasted with this issue already. It’s a pity.

Note: This is just an information. The models here are still in the 1.1 state, and will be updated to 2.0 and added to the official Khronos repo when the dust around 2.0 has settled.

I have created a new (still: preview) release at https://github.com/javagl/JglTF/releases/tag/v0.0.0-alpha05
