Can't add a key to my curve

Hello, I’m very new to UE4 so my problem is probably super-easy to solve. I want to change my particule color over life, so I created the module but it is impossible to add a key to the curve.
I’m following a video tutorial, and the guy say “press ctrl then click on the curve” but it’s not working.
It’s like the curve editor is locked or something…

Thank you very much

That’s really strange, did you figure this out?

I’m having the same issue. Cannot create any new keys. I’m also completely new so maybe we haven’t turned on the ability to add a key?

Hi -

Just to make sure we are one the base line here, you are selecting the module and clicking on the graph button on the module and then Ctrl-Click the resultant graphed line in the Curve Editor?

Thank You

Hi,
Be sure to choose “Distribution Vector Constant Curve” in detail panel, and not “Distribution Vector Constant”, which is by default.
