When loading buildings into Unreal Engine via a URL in Cesium, my computer slows down significantly. It seems to be a resource issue. Is there a way to adjust the number of buildings or the area being loaded?
What tileset is this, and how was it created? I ask because sometimes this can indicate that the tileset you’re displaying is not structured well, so rendering a view requires far more tiles and resources than it should.
If your system does not have much GPU memory available, it can be useful to reduce the “Maximum Cache Size Bytes” property. You can even set it to zero to minimize memory usage. It will not affect which tiles are loaded and rendered, but it will cause tiles that are not currently visible to be aggressively unloaded. The downside is that revisiting a previously-visited area will require loading the tiles again.
Of course, the ultimate way to reduce resource consumption - at the cost of rendering quality - is to increase the Maximum Screen Space Error property. Changing it to 32 (from the default of 16) will drastically reduce the number of tiles that need to be loaded and rendered in most tilesets.
