Google Photorealistic 3D Tiles and Polygon Raster Overlay

I want to replace the road assets from Google Photorealistic 3D Tiles with my own assets. I tried adding a Polygon Raster Overlay according to the documentation, but this causes Unity to always force close without any error message and consumes a huge amount of RAM. This also happens after building the project.

Is there a way for me to use this, or maybe an alternative approach?

My goal is not only to replace the road assets but also to remove the objects that block the roads provided by Google Photorealistic 3D Tiles.

Hi @t_dae, welcome to the community!

Can you tell us more about your polygons and how you’re using them to populate a CesiumPolygonRasterOverlay? In particular, are there a very large number of polygons, or are they very complicated?

Sorry I don’t have a solution, but I wonder if this is related to Google Photorealistic 3D Tiles Cause Crashing with CesiumPolygonRasterOverlay polygons populated ?

Hello, thank you for your response.

I’m trying to replace the Google Photorealistic road assets with my own so the roads appear clean without extra objects. This works fine with Bing Maps Aerial, but with Google Photorealistic (both in Unity Editor and the built .exe), Unity closes after a few seconds with no error message.

The crash even happens in the Editor when the game isn’t running — for example, just moving the camera in the scene causes Unity to suddenly close.
