In Compositor, some nodes do not have input socket for that value. Can I change these values at once?

Compositor Node Group

For example, my node group has Distance input socket. I want to use this value to Distance value of Dilate/Erode nodes, but there are no input sockets.

I know it can be done with Python script or with Driver, but I want change it only within Compositor.

Just add a Value node and use it with a driver. That counts as within compositor, right? :)

  1. Add a Value node
  2. In value field RMB > Copy as New Driver
  3. In Distance field RMB > Paste driver

enter image description here

Thank you @JachymMichal! It also worked with input values of node groups.
