Making sure a billboard is always on top of another billboard

Hi,
Is there a way to make sure a billboard is always on top of other billboards?

Something like the “raise” in primtiveCollection?

Try setting the z value of the eyeOffset.

Thanks.
It doesn't work for me (at least I can't see any change...).

Any idea why?

Reaching into the primitive like that won’t work because that primitive is managed by the DataSource and any changes you make under the hood may/will be overwritten.

The correct way to do it is modify the entity itself, I’ve updated your fiddle with a working version: http://jsfiddle.net/7npv52r6/

Starting with 1.6, you won’t need to use Cesium.ConstantProperty and will be able to assign directly.

Thanks.
Works great!
