Hi, I’m newbie with shaders and I didn’t use matrix for a while… (I’m not Neo :smile:) I want meshes face to the camera only on 2 axis I know it’s like billboard and I can take a look on THREE.Sprite but I’m not able to make it working… From three.js sprite vertex glsl: uniform float rotation; …

Just recalled about this topic, surfing @hofk ’s collection of examples. Seems it works with InstancedMesh and slightly modified MeshBasicMaterial ( modification ), in which you pass a quaternion in uniform: https://jsfiddle.net/prisoner849/g8j24z0n/
