Duplicate textures (textures are embedded and not externally referenced)


Let’s say I have a million buildings using the same facade texture.

My dataset is consisting of one CityGML file, referencing a single external image file.

When I import it through Cesium ion, my asset is tiled and each b3dm tile is embedding the same texture data.

Ideally all tiles should reference the same external image file.

Is that possible to do that?

Thank you.


You are correct in your assessment that the texture will be duplicated once per tile and at this time we do not use external textures as part of the 3D Tilesets produced from CityGML.

We’ll create an issue to support this, but don’t have a timeline when it may become available.
