We have released a new version of Online Maps asset, in which new features are added and problems found are fixed.
[Buildings] Added ability to ignore height tags.
[Core] Fixed memory leaks.
[Core] Fixed map shift on smooth zoom.
[Drawing API] Added the ability to line follow relief (OnlineMapsDrawingLine.followRelief).
[Key Manager] Added Mapbox.
[Tileset] Added TilesetDrawingElementZTestAlways shader.
[Other] Improved asset folder search in the project.
[Other] Added classes for loading vector tiles.
Important: this is not a final solution, and Online Maps cannot yet display vector tiles.
This is only a small, and very important step in this direction.
But it does provide ways for professionals to do awesome things with vector data.
