Drawing a color block

Does the plugin have the ability to draw regions (like cesiumjs), such as identifying four points and drawing a color block in the middle

I’m afraid we don’t have this functionality. This might be possible in part if we had the RasterizedPolygonsTileExcluder class, but we haven’t gotten around to implementing it. We have an issue to track that here: Add support for RasterizedPolygonsTileExcluder · Issue #64 · CesiumGS/cesium-unity · GitHub
