Please add some more details to your report. It would be great if you can demonstrate the issue in a live example, too.

Thank for your feedback very much. I had test the three api versions (0.94, 0.95,0.96), Raycaster is not work on Sprite.
In this example , the web address is 'https://threejs.org/examples/?q=int#canvas_interactive_particles', the bug can show. Thank for you help very much. Wait for your feed back!

Raycaster no longer works with Sprites using CanvasRenderer and WebGLRenderer.

I don't think that's true. This example uses WebGLRenderer and works:

Um, I guess this bug was introduced via #14292

At least on problem is that SpriteCanvasMaterial does not have a rotation property. So cos and sin become NaN values in the following code section:

three.js/src/objects/Sprite.js

Lines 107 to 114 in d1ba0bc

	var rotation = this.material.rotation;
	var sin, cos;
	if ( rotation !== 0 ) {
	cos = Math.cos( rotation );
	sin = Math.sin( rotation );
	}

My fault, I will make a PR to fix it.
