p.y *= OnlineMaps.instance.transform.localScale.x;

It did the trick ! Thanks a lot.

I will consider using Online Maps v3 beta after my next dead-line

In Online Maps v2 only smooth zoom emulation, which is achieved by scaling the map GameObject.
This means that in fact it does not change the corners of the map.

So after a deeper investigation, i noticed that there is no problem when my LineRenderer points have an altitude of 0.

The unwanted behaviour must be the result of this particular line in the GetWorldPositionWithAltitude function:

float yScale = control.GetBestElevationYScale(tlx, tly, brx, bry);

With tlx,tly,brx and bry beeing the result of map.GetCorners(out tlx, out tly, out brx, out bry);

I supposed that the corner of the map are not updated when the zoom is "in progress" between two levels so i tried to call "OnlineMaps.instance.UpdateCorners();" before trying to call "map.GetCorners" but it didn't solve my problem

Hello.

If you are working with a smooth zoom, I highly recommend you try Online Maps v3 beta.
Online Maps v3 has a built-in float zoom, and it will be MUCH easier to solve your problem.

To make it work in Online Maps v2, you need in GetWorldPositionWithAltitude to multiply p and transform.localScale.x of the map.

I have a lineRenderer. It does redraw when the event OnlineMapsTileSetControl.OnMeshUpdated occurs, which allow me to keep it in the correct position when moving the map.

But, when i'm zooming "too much" (when i'm beyong the max zoom level -> i use an android tablet so as long as i don't release my finger when zooming i can go beyong the max zoom level) the lineRenderer is in an incorrect position.

As i don't want to wait for the user to release his finger to draw my lines in the correct position, i tried to use OnlineMapsTileSetControl.OnSmoothZoomProcess to update the lineRenderer constantly when zooming.

But it doesn't solve my problem.

OnlineMapsTileSetControl.OnSmoothZoomProcess is working though. (i can see my Debug.Log messages as long as i don't release my fingers).

Here is a GIF for a better understanding of the situation:

What am i missing ?
