About Shader and Texture
Hi,
I read this article (here) and try it on my project, but it doesn't work.
Whatever texture changed, it didn't show difference.
I uploaded two pictures (sea and forest for test).

Then use this script to change texture and shader.
$scope.init = function(){
//$scope.setWidgetProp('model-1', 'texture', 'app/resources/Uploaded/sea.jpg?name=tex0&edge=repeat');
$scope.setWidgetProp('model-1', 'texture', 'app/resources/Uploaded/forest.jpg?name=tex0&edge=repeat');
$scope.setWidgetProp('model-1', 'shader', 'reflect;mixer f 0.5');
};
angular.element(document).ready($scope.init);
In runtime, it look like that.

Did I miss something?
