uniform variables error after updating model from gltf v1.0 to gltf v2.0

[liukangkanglkk99]

I am trying to update model from gltf v1.0 to gltf v2.0.
The following may occur in a gltf file:
"techniques":{ "a":{ "uniforms":{ "u_tex":"tex", "u_tex2":"bakingTex" } }, "b":{ "uniforms":{ "u_tex":"bakingTex" } } }
But in the function moveTechniquesToExtension(gltf) of moveTechniquesToExtension.js,
the mappedUniforms variable is finally recorded as bakingTex -> u_tex and bakingTex -> u_tex2 information is missing.
This leads to errors in later use of uniform u_tex2.

@liukangkanglkk99 Thanks for all the details, it should be quick for us to track this down. If you are able to share the glTF that would be helpful too.

@liukangkanglkk99 I opened a fix here: #490.

Would you mind trying it out with your gltf?

With pleasure. I tested this and it does work.
