Hi Kristian,
I've been playing around and found an "undocumented/unsupported" way to do it....
Using the the following sample: http://jscore.esri.com/javascript/sample-code/sandbox/sandbox.html?sample=scene-local
If you add the following code after the view is created, it will "turn off" the grid:
var terrain;
view.then(function () {
terrain = view._basemapTerrain;
terrain.on("load", function () {
terrain.opacity = 0;
});
});
So the only bad part here is accessing the private _basemapTerrain property. So maybe a basemapOpacity property could added to the SceneView (or something like it)?
Cheers,
Christian.
