 * Addesses existing issues with babylon.js serialization:
 * 1) technical: gltf serialization doesn't support transparency, json serialization fails with with js errors
 * 2) generated json files may be huge
 * 3) intelectual property violation - even with open source models, we must comply with the license
 *
 * So we take mixed approach to serialize everything - some custom and some babylon.
 * Most important is not copying everything, use URL of the model whenever possible.
