@sean_lilley, I’ve made some progress (thanks to you!). But I have a number of things to work out.
Each flight has it’s own instance of the Material, MaterialAppearance, CoplanarPolygonGeometry, and the Primitive that is created from those.
However, there are 3 issues I’m running into immediately:
- It appears that all of the heatmaps are the same as if there is something being cached and all the aircraft are using the cached data. I know GLTF models have a “cacheKey” and if they share a common cache key then they share textures. Is that what’s happening here?
- There are places in the map tiles that occlude the heatmaps. See the heatmap in the lower, right portion of the image above. This happens in various places on the map/globe. Is there a setting to make the heatmap be visible above other terrain?
- When I turn the heatmaps on I instantly get results for all the aircraft. But after some amount of time (it seems to vary… but maybe 20 to 30 seconds) all of the heatmaps go away. If I wait long enough they come back. I’m not seeing any errors. I don’t know if this is maybe a memory issue. Or if there is a caching issue causing all flights to share the same texture maybe the flight with the shared texture goes out of view and causes the issue?
I’d really appreciate any thoughts/suggestions you might have (particularly regarding the first 2 issues)!
