Cartographic Polygons in Unreal

I have the cartographic polygon system working great in Unreal. But had a question. I know that the red channel is the mask for the ML_CesiumRasterOverlay. This indicates whether or not I am rendering something that is inside of one of the polygons I’ve laid out.

But is there a way to know which polygon I’m in? I’d like to use the same MLB to tint different polygons different colors without having a layer for each color…

Many thanks!

Hi @jknutz, welcome to the community!

At this time, there is no way to distinguish polygons from each other within the material. However, feel free to submit a feature request for this on our Github repo! We’d love to know about your use case and needs; these details will inform how we assess the feature for our roadmap.

Thank you!
