I want to interactive with CesiumCartographicPolygon Actor,
And I use Line Trace By Channel,
But I can’t Hit CesiumCartographicPolygon Actor, It seems no collision right？How to Hit or interactive with it?
To my knowledge, we don’t generate physics meshes from cartographic polygons. What functionality are you trying to achieve? Maybe we can suggest an alternative.
Thank you for your reply.
I just use cartographic polygons to tint an area,
And I want do some interactions with it, like Cesium for Unreal Samples.
To achieve interaction, first of all, I need to hit it.
But I can’t hit it using line trace by channel, I’m stuck here.
The Cesium for Unreal Samples level demonstratse metadata picking and styling. In other words, it takes advantage of the
EXT_feature_metadata extension in the model. (Later, support for
EXT_feature_metadata will be dropped in order to support
Line Trace By Channel can then retrieve the metadata values on mouse click, using the Cesium for Unreal Blueprint API.
I don’t believe this is reproducible with the Cesium Cartographic Polygon unless you turn it into actual 3D geometry that can then act as a physics mesh. Perhaps you could make a 3D version of the polygon yourself, or some other 3D volume, use it as a collider?
