Hi,
In the latest release we have changed our index.html.
So you have to update your custom index.html as well.
Following code:
<script type="text/javascript">
window.onload = function () {
var config = new WALK.SceneLoadConfig();
WALK.init(config);
};
</script>
has to be changed to:
<script type="module">
WALK.ASSETS_URL = "./";
</script>
