The time it takes to load map for any area is very much dependent on the internet speed as we have to stream resources in before they can be displayed. It is possible to cache resources so it loads much faster once the resources are downloaded. You can find an example of precaching here: https://www.wrld3d.com/unity/latest/docs/examples/precaching-map-data/
I have 250 MBit/s internet connection, also tested on LTE. The problem occurred 3 week ago. Sometimes the map appears in a moment after start, but sometime in a minute. Precaching map data doesn't help.
Can you provide us the following details so we can further investigate this issue?
I have shared the details with our engineering team so we can investigate and resolve the problem.
Yes, the problem still occurring about 3 weeks. I'm testing my app on New York. The start location is on Empire State Building. But the problem also in SDK's default locations, even on empty project.
I've been working with WRLD SDK from April 2020, without any issues.
Right now I made 5 runs: 3 times - instantly, 2 - up to 1 minute idle.
We are having trouble reproducing this issue. We have tested with Unity 2020 and Unity 2019 LTS with WRLD Unity SDK v0.8.17. I understand that you have mentioned that you are seeing this issue on all platforms but just to try and narrow down the problem, can you provide us with the following information?
Which city and country you reside in? In case this is an issue with our CDN's cache for your region resulting in delayed load time for map resources. OS information (e.g. Mac OS 10.15.7). Unity version (e.g. 2020.1.0f1). WRLD SDK Version (e.g. v0.8.17). Selected platform in Unity Editor(Android, iOS etc)
It would also be very helpful to us if you can provide a minimal repro project in which the issue occurs or a video showing the problem.
Another thing that I would suggest trying is clicking inside the Game View in Unity after pressing play in Unity Editor. WRLD Maps do not stream if the game view is out of focus so it could appear the stay idle until game view comes back in focus.
My location is Russia, Izhevsk.
Mac OS Big Sur 11.0.1, Unity 2018.4.30, 2019.4.15, 2020.1.15 Mobile devices with iOS 14.2, Android 10. Wifi and LTE. WRLD SDK Versions 8.0.14, 8.0.17, 8.0.37
Empty project with SDK only.
May be I can sniff the network packages and found some informations? What network address to check?

It is really looks like CDN issue. Just tried with VPN connection from other country - no issue! Pls check Russian CDN
From the video it looks like you are clicking on other windows immediately after pressing play. The map loads fine when the game window is in focus. But whenever you click a GameObject in the hierarchy for example, the game windows is no longer in focus and the map does not update until you click back on the Game window bringing it back in focus.
Whenever you just press play and wait the map loads immediately as seen in the video. I understand that this is an esoteric behavior but as I mentioned in my previous response, WRLD Map stops streaming if the Game windows is out of focus.
This is only relevant in Unity Editor and will not be present in any Builds you make with WRLD Unity SDK. I will suggest our engineering team to look at improving this behavior or perhaps make it more prominent in our docs to avoid any confusions.
I know. I keep GameVIew in focus. Anyway, I found that there are no issues with VPN. Pls check your CDN.
As far as we can see, once the map starts loading (black/blue grid appears) all of the resources arrive very quickly, so it's likely not an issue with the CDN. The first thing the app does before the map starts is authenticate itself with WRLD.
Can you try running the following command in the terminal and see if there is a delay returning a result?
curl -v https://apikey.wrld3d.com/validate/?token=YOUR_API_KEY_HERE
Some other things you could investigate:
The issue is still here.
I caught this:
This response appears after map is loaded. If map loading has delay, the response has too.
Hi, that DNS request looks normal. Did you try any of the debugging steps I suggested earlier?
I found the issue:
server-13-33-243-111.hel50.r.cloudfront.net is unreachable from my place.
When map loading has a delay I see "server-13-33-243-111.hel50.r.cloudfront.net:https (SYN_SENT)"
UPD: 13.33.243.111 it's not pingable, but with VPN it's pingable
UPD2: So, this ip is blocked in Russia by the tribunal's decision in 2013 :(
Description
Long WRLD map initialisation. I faced with long WRLD map initialisation. No matter which OS and platform. Often I have to wait for 1 minute It Looks like server's issue.
Steps to Reproduce
Create empty project. Import WRLD SDK. Run UnityWorldSpace scene. Stop. Run again.
Expected behavior: map should load after run the app
Actual behavior: map loads after 1 minute
Reproduces how often: 80%
Additional Information
Any platform, any Unity version, any WRLD SDK version.
