Prevent wide beam particle emitter from rotating towards camera

I’m trying to make a particle system for a weapon which shoots a flat wide beam, but having some difficulty. I was able to make something close to what I wanted using a beam emitter with a large X size. But, the problem is that I can’t figure out how to force it to always be flat and not rotate towards the camera.

The particle system is spawned attached to the weapons muzzle, and the target is set as the result of a singe line trace. Everything seems right except that it rotates slightly to face the camera. Is there any way to prevent that? I’ve tried everything from using Orientation Lock Axis, to every type of Screen Alignment available and can’t figure out how to get the desired result.

Here’s what I have set up right now:

Did you ever figure this one out? I am having the same problem.

Bump. I can’t figure this one out, either :confused:
