Elevation & Buildings

Hello.

The problem with buildings for Russian users is solved by using another (unblocked) server.

Let's talk a little about your problem:
The application works correctly on some computers, so most likely the problem is not on your side.
Buildings or elevations may not be displayed if for some reason Online Maps cannot download data.
Buildings and elevations use data from different sources, and users have problems downloading data from both sources.
When this can happen: only with problems with Internet access on these PCs.
There are many things that can cause such problems, for example a firewall.

So you need to check what causes problems with Internet access on these specific PCs.

In the first post you mentioned that PCs are in college.
With a very high probability, the college has a firewall on its side (not on the user's PC), which strongly filters requests.

Use OnlineMapsWWW.OnInit to intercept all requests and show it in the log.
Next, find requests for downloading elevations and buildings.
Copy it and try to open it with a browser. Most likely this will not work.

If so, you will need to change the data sources.
For elevations, try using ArcGIS Elevation API.
For OSM you need to change the server.

You can do this in two ways:
1. Modify the request using OnlineMapsWWW.OnInit.
2. Modify URL in the class OnlineMapsOSMAPIQuery.

No, most likely it is not related to a netframework or graphics card.

Let's look at all the places where the problem could be:
1. Before OS: Internet provider, router and other network equipment. The probability of about 10%.
This is quite a rare case, but it can still be.
For example, OSM Overpass API (main server) is blocked in Russia.
2. OS and applications (for example, antivirus and firewall).
The probability of about 75%.
Win10 is a repository of unusual things that shouldn't happen, but happen.
I have many examples of this, and most likely you also have them.
3. Unity. The probability of about 5%.
4. Online Maps. The probability of about 10%.
5. Third-party scripts. Probability is unknown, because you did not write about them.
But theoretically it is possible.

How to check where the problem is.

1. Open URL in the browser.
If it works, then this is not a problem 1.
2. Open URL using the application made in Unity.

If it works, then this is not a problem 2 and 3.
3. Subscribe to OnlineMapsBuildings.OnRequestSent, and when this is called, subscribe to OnlineMapsBuildings.osmRequest.OnComplete to check what you have in response.
If you have the correct response, but it does not work, send me a screenshot of Online Maps (Script) and Online Maps Buildings (Script).

Most likely here is one cause of the problem with elevations and buildings.
So finding and fixing the first problem, you fix the second.

This is CultureInfo problem in dotNet4.x.
For example: (4.5f).ToString() - may be "4.5" or "4,5" depending on the region.
This problem has been fixed in v2.5.51 and v3.0.0.31 beta.
What version of Online Maps do you use?

To fix this problem, you need to modify VERY MUCH things in the scripts.
So here I just can't say something like: modify that variable / line / method.

No, you do not need to update to Online Maps v3 right now.
Online Maps v2.x will be maintained at least until the end of 2019.
So you can simply update to Online Maps v2.5.52 (the latest version 2.x).
This will not require you to make any changes to the project.
