Line Renderer Keys don't work

Question

Hi, I am creating a game and I am using a line renderer for a laser. I want the laser to bulb out in the front, then go back to its normal width. I tried to add keys in the AnimationCurve but it didn't seem to change anything. The only keys that worked were the first and last. Sorry if I am using the wrong terms, I am a beginner! By the way, I asked this question before but it is taking a long time for moderation. That is why I am posting this in the help room.

@gawynross, You need the [edit this is incorrect: same number of points] - you need more points in the lineRenderer than the number of line thickness keys. Create a lot of points and you'll get a smoother buldge.

Test by creating an empty object and add a lineRenderer component, add 3 points at 0,0,0 - 0,0,1 0,0,2 and then set the thickness keys on the curve.

Play around to see the effect of moving the keys left or right.

To make a laser that bulges at the start and grows toward a target will be an interesting challenge.
