Hello . I’m trying to rotate one object relative to another. But it’s not like it doesn’t work so that when the slider changes, it’s smooth.
In 1 case, I managed to make it rotate, but there it constantly adds value when the slider changes.
In 2 cases, I managed to make a smooth rotation, but for some reason it rotates relative to 0 coordinates.
Help solve the problem.

createdialog RelativeTransformRol escapeEnable:truethe most complicated part is to organize the right UI and parameter notifications. I would probably do it using a CustAttribute(s).

denisT thanks for the hint. I completely forgot about – prerotateX.
I modified it a little here, as I needed the selected objects to retain their original transform relative to the pivot point. And after changing the slider, it returned back to 0 and the offset transformation was saved.
If you can optimize it a little, I’ll be glad to see it. Thanks in advance.

True, this does not work with biprd objects.
