Call 'asapUpdate()' on your Op after you make the changes, but it's not clear from your post how the output of the node changes based on mouse movement.

Using Knob->set_value() to do so. Can see the values changing all the time while dragging the mouse, but the plugin doesn't get re-rendered until mouse release. How can I force the plugin to re-render? I was expecting the node working similar to a grade node when you use the color picker, that constantly updates the image so you can easily see what the result is... Thanks in advance, Cuco Bures P.S. Btw, is there any better way to set the values of the knob other than that?
