How can I tell if a texture or model has loaded completely into the scene?

We will have the ability to know when the object is fully streamed in. Expect this in the next version we release.

We do have a workaround which involves checking to see when a texture has been downloaded. You can do a get property command to check for a certain texture and then run a function to trigger the animation. There is an example you can look at. The texture being called is called "MTSTexture.tea_picture".
