Indeed, I found a bug. You have to edit the attribute "Radius", remove the numeric range, save and reload.

Ok, thanks :)

How about limiting the circle to arc, is it possible? :)

I'm guessing it requires heavy use of gradients and expressions and the problem is that I am not very good on either yet :oops:
But tell me, was that made without scope and am I guessing right above? :)
Or can you even give some hint? :mrgreen:

HA! I'm close, trick is using UV in gradient, needs some development still, though :mrgreen:

Do you approve my way of doing it or did you do it some other way or have improvement ideas to add to my version? :)
