Maps huge memory usage

Hey Alex,

Thank you for the quick response! I have a 2D game, so I thought I would use it in 2D, tileset was only in 3D available. I'll try to convert it to tileset/3D. The map is only part of the game, so I need it to be loaded on a tab and also start the load there.

I found it with an xcode Build/Run when I kept scrolling ons the map, I saw in xcode that memory kept increasing and never dropped down.

Kind regards,

Julian

Xcode shows you the overall memory usage of an application that also includes Unity Engine itself and your assets.
So here to say that the map uses 500 megabytes - this is not correct.

Tileset may be different.
Set the camera perpendicular to the map and it will look like a 2D map.
Or you can use Render Texture to display the map on UI.
Online Maps v3.8 will have an example for this.

Unfortunately, I did not understand your questions about custom markers.
Please rephrase this.

Thanks for the video, it is very useful.
But, unfortunately, this is not particularly applicable here, because in addition to zoom, you need to keep in mind:
- jump through 180 meridian;
- changing the position and / or size of the map in the scene;
- changing the position of the camera (for example, when you rotate or tilt the camera using Camera Orbit);
- updating elevation data.

This can be implemented in specific projects when you know for sure that these situations will never happen in your case.
But to make a general example that will use these optimizations is not possible, because immediately there is someone who will say that this does not work for him because of something.

Hi!
1. I have the same problem in my case:
Tileset control is used.
512 x 512 tiles are used, texture compression is disabled.

At the moment the memory cache decided it filled 10 MB Unity profiler shows growth of about 600 MB in textures.
What i've tried (did not help):
- set memory caches size to 1 / 50 / 150 / 200 MB;
- temporary change the size constant in MemoryCacheItem from 30 000 to 1 000 000;
- set Online Maps : Advanced : Count Parent Levels from 5 to 0.

Also the problem is reproducible in an empty project:
- create an empty Unity project;
- call GameObject -> Infinity Code -> Online Maps -> Map Wizard;
- check Move camera to Map, press Fix camera near, far.
- chose OpenStreetMap:Mapnik;
- press Create;
- play in Unity editor and start continuously zooming in and out while watching the Unity profiler : Memory : Textures.
It starts from 100 MB, grows to 200 MB and drops to 170 MB on memory cache clearing. But suddenly starts to grow indefinitely (was able to get to 500+ MB).
The same bug is also reproducible in case of default (in wizard) map provider ArcGIS (Esri):WorldImagery but requires to zoom longer.

2. Connected question about memory:
Disabling the map GameObject while zoom == 1 leaves the map on the minimum level of textures memory consumption. But it is not the case if disabling while zoomed in.
I'm setting zoom = 1 on the next map GameObject activation. And it resets memory to the minimum level. But setting zoom == 1 in OnDisable() does not free memory.
I would like to leave the map on the minimum memory level in every case when I do not need the map and disable the map GameObject.
What i've tried to call in OnDisable() (did not help):
- set zoom = 1;
- call OnlineMapsCache.ClearMemoryCache();
- call OnlineMaps.tileManager.Reset();
Also tried to destroy and recreate the map GameObject from prefab (instead of disabling) every time I need it. But it increases textures memory for about 2 MB on every creation.
