Along with a host of other revisions and new features in Mantle 1.3 comes Mapbox Custom Style support!
For those of you using Mapbox Studio to create custom styles for your projects you can now directly load your custom style image tiles directly into Unity via Mantle as an image overlay with the standard support for generating buildings, landuse areas and of course Mantle's granular styling system to procedurally decorate it with 3D objects and textures.
All you need to get it working is a free Mapbox account and to copy your username and map style code from inside Mapbox Studio and voila.
If you're not currently using Mapbox it's worth pointing out that they're now releasing premium styles for users to add to their libraries such as the recently released Moonlight style. What this means for you is a load of professionally designed map styles for free that you can now bring directly into your Mantle scene, draping over landscape and buildings.
It's a feature we've been asked for often and we're pleased to finally be able to make it available in 1.3 coming to the Asset Store shortly!
