I'm a Nuke noob, but with this Gizmo I'm perfectly able to simulate the edge softness of an Angeniux zoom. However, the aberrations turn out red, and not blue as on the real lens. Would you consider adding a function to tweak colours in the future?

Sorry for the late reply, but I added an option to bypass the R,G or B channel to possibly achieve the look you are going for.

Really cool Gizmo! But I get this error when rendering:
ERROR: Group2.Sharpen1 .disable: Nothing is named "usmask" . It seems like there is a broken expression.

Hey Fynn, I fixed the "usmask" error and uploaded a new version of the Aberration gizmo. (V1.4) Let me know if this works. Thanks.

Hey Jason. Thanks for the quick update. I think you might have uploaded the wrong file though. The version displayed at the bottom of the gizmo is the same and the error persists.
It seems like there might be other expression errors in other nodes and there's a viewer inside the group/gizmo (in my experience having multiple viewers, even if they are not open and inside a group, tends to slow down playback in the comp a lot). Hope you have time to fix this.
