Changing uniform values for shader in gltf model using KHR_techniques_webgl

CesiumJS
1

Hi,

I have started using KHR_techniques_webgl with my gltf models and it works nicely so far in Cesium (I am using 1.50)

What I am trying to achieve is to change uniform values so I can control dynamically some of the shaders parameters.

I haven’t found a way to call getMaterial as my material does not have one, as in the example

“materials”: [ {

        "extensions": {
            "KHR_techniques_webgl": {
                "technique": 0,
                "values" : {
                    "u_light0Color": [
                        0.8,
                        0.8,
                        1.0
                    ]
                }
            }
        }
    }
]
