tile with png file


I want to load cesium with png file as tiles in a way that the seas will be transparent, and users will be able to see the background instead of the blue in the map.

I am loading tiles with png file but instead of transparent I see blue color.

Is it possible?



Can you share a Sandcastle example of your imagery layer, or an asset ID on ion? It should support transparency. Unless you mean that the imagery layer is indeed transparent, but you don’t want the underlying globe color to show?

If so, you could remove the base layer and change the globe color to a custom one: see https://cesiumjs.org/Cesium/Build/Documentation/Globe.html?classFilter=Globe#baseColor

This is what I was looking for:
