After updating from three.js r62Dev to r64 or r64Dev I am receiving the following error.
var radarMaterial = new THREE.SpriteMaterial( { map: radarTexture2,
SpriteMaterial.alignment
and SpriteMaterial.useScreenCoordinates
have been removed from Threejs. See the release history: https://github.com/mrdoob/three.js/releases.
Sprites are now rendered in the scene just like any other object.
If you want to create a heads-up display (HUD), the work-around is to overlay a second scene of sprites, rendered with an orthographic camera.
See http://threejs.org/examples/webgl_sprites.html for an example of how to do that.
