Cesium OSM Buildings not removed in "play" mode when "Cartographic Polygon" is added

Cesium for Unreal
1

Hello,

I have a critical issue that i need to solve as soon a s possible.
I have Project inside Unreal Engine 5.7
I use “Cesium for Unreal Engine” Version 2.22.1

I have placed “Cesium Georeference0” and “CesiumOSM Buildings”
(Note i do not have terrains") I have my own terrain inside unreal engine (not via Cesium).

And i use “CesiumPolygonRasterOverlay” applied directly on “Cesium OSM Buildings”
And here are two issues.
Problem 1. When i open up project rasters are not taking effect instantly. (They start to work when i add or remove one raster when i click on “Add Element” (see the picture)

Problem 2:
When i click on “Play” rasters do not take any effect. All buildings i see are back on visible. But i need to delete buildings where raster is applied.
End goal is to package the project so i can view it on other pc-s also

Hey @ISUther ,

Firstly, the latest version of Cesium for Unreal on the Unreal Marketplace/fab is v2.24.1 so it may be worth it to update to see if that resolves your issue.

Have you tried using one CesiumPolygonRasterOverlay with multiple polygons rather than multiple CesiumPolygonRasterOverlay?

If this doesn’t resolve your issue, if you could provide detailed steps to reproduce this issue in one the the Cesium for Unreal Samples levels, along with some screenshots of desired affect (sounds like it displays in editor correctly?) and of the issue after you click play. This would go a long way to us helping you with your issue.

Cheers!

It is weird. Now when i removed and re-placed them it works fine.
I keep you updated if this issue occurs again.
