Hello,
Due to some script related dependencies I have to rotate my map object in the scene. It's basically got a rotation 0/180/0 e.g. upside down than the default rotation. This, however causes an issue with the HorizonWithoutElevation script. The content of the map on the horizon tiles doesn't fit the main map. Any quick way to fix this while still keeping the 0/180/0 rotation of the map object?
Cheers,
Jürgen
It was not planned in this script that the map could be rotated.
Email me (support@infinity-code.com) and I will send you a modified script.
How do you use the scripts you publish?I used horizon. Cs directly.This is the error I got:
Assets\Infinity Code\Online maps\Scripts\Horizon2.cs(76,45): error CS0117: 'OnlineMapsUtils' does not contain a definition for 'GetWWW'
Assets\Infinity Code\Online maps\Scripts\Horizon2.cs(79,18): error CS1061: 'OnlineMapsTile' does not contain a definition for 'customData' and no accessible extension method 'customData' accepting a first argument of type 'OnlineMapsTile' could be found (are you missing a using directive or an assembly reference?)

For Online Maps v3 you need to use Horizon2_OM3 script.
For Online Maps v3 you need to use Horizon2_OM3 script.
Thanks，But ，I used the script you mentioned, but my program did not get OnlineMapsBingMapsElevationManager.instance：
This example requires Bing Maps Elevation Manager.
If you don't need elevations, see HorizonWithoutElevation script in the package.
Horizon 2 ArcGIS has many ways to fix this:
1. Decrease Position Y Offset, for example to “-25”.
2. Decrease In Map View Y Offset, for example to “-70”.
3. Increase Render Queue Offset, for example to "300".
Hi Alex, playing with elevation with the horizon_OM3.cs and the elevation manager, I wanted to have the small detailed map above the horizon one in the rendering. I wanted the y position at the same level for both the first option but then there was some overlap with the first option so no. I fail to see the purpose of the In Map View Y offset, could you explain a bit more?
I tried the third option but I've read that on the URP we had to set the ZTest property of the material to Always so that it shows up alwais on top.
The urp and shadergraph does not expose this property. The solution for me then was to play with the camera stacking with base and overlay, and have as many renderPipelineAsset and layers as I needed horizons.
I found this path a bit tedious but it works well, and I thought maybe there was a simpler option you had come up with?
Thank you for your time 
Unfortunately, I am not an expert on shaders, and each of them was given to me through a lot of pain.
So I can't tell you which way is better here.
Hello Alex, I'm trying to figure out why Horizon keeps generating this kind of offset in the terrains around my central map?
This is right from a fresh map add with all values set to 1024
mapsissue.jpg 82.44 kb, 12 downloads since 2022-04-29
These scripts always use whole tiles, and it can have some offset from the main map.
You need to adjust Camera / Clipping Planes to make the user not see it.
Alex, how would I go about adding markers to the horizon terrains?
I'm using the Bing maps version if it matters
The horizon is not part of the map and cannot have markers.
ugh, ok, gonna have to come up with a different solution then, it looks so bad seeing markers just disappear when they hit the horizon terrains
Have a look at OnlineMapsMarkerFlatDrawer.OnCheckMarker2DVisibility. Using this event, you can change the visibility check rules and make the markers visible from the outside of the map.
Hi Alex,
I have read the thread above. I am getting NullReferenceException "if (OnlineMapsElevationManagerBase.isActive) OnlineMapsBingMapsElevationManager.instance.SetElevationData(heights)" at this line in "Horizon2_OM3" script.
I am using source as Mapbox, Satellite in onlineMaps component. And Mapbox elevation component on the maps gameobject.
Is there anything wrong I am doing?
As in one reply you have mentioned to use this "Horizon2_OM3" script with mapbox and in one reply you said it to use with Bing. What is the right way to use it with mapbox?
Also I want to use it for cached data, how to that too. Please help me do that.
Thanks,
Pooja Garg
Hello.
Horizon2_OM3 requires Bing Maps Elevation Manager.
This will download the elevation tiles from Mapbox and pass them to Bing Maps Elevation Manager, so you won't actually be making requests to Bing Maps Elevation API.
Hi Alex,
Thanks for the response!
Can change "Horizon2_OM3" script from using BingMaps by setting elevation data like this "OnlineMapsBingMapsElevationManager.instance.SetElevationData(heights)" to using "SetElevationTexture(Tile tile, Texture2D texture)" in "OnlineMapsMapboxElevationManager" script.
Also how will Horizon2_OM3 script work with cached data?
This script does not cache elevation data.
My goal was to give an example of how to show a map outside of a map in order to extend this, and not to make some kind of universal solution.
I think, there is some misunderstanding.
My question is, if I have already cached data for some region then how can we use this Horizon script to load cached tile textures and elevation data from cached folder in offline mode.
Modify the script and before downloading the elevation data, check its presence in the cache.
If present, read the data from the cache.
If missing, download the data and cache it.
Hi Alex,
Thanks for the help! It really gave me direction.
I have added the code to load the elevation data from cache using "OnlineMapsCache.Get(string key)" while keeping internet off.
But something wrong must be there, I am not able to load the cached elevation in offline mode for horizon.
Does any of the Horizon scripts you have shared in this thread has the feature to load the elevation from cache?
Please help me into this.
Regards,
Pooja Garg
You can use OnlineMapsTiledElevationManager.SetElevationToCache and TryLoadFromCache as an example of writing to and reading from a custom cache.
