Compositor: Driver value won't trigger a redraw
Closed, ArchivedPublic

Description

Duplicates: T26764

I wanted to use a 3D object to modify values of nodes in the compositor.

1.So I set constraints to the object and
2.I added a Value Node in the Compositor.
3.I added a driver to the Value Node.
4.I pointed the Driver at the object value.

But I can't get the Compositor to update after each change (in the 3D window). However the driver value in the "Value node" does change. Other (direct node value) changes trigger a compositor redraw, just not driver values.

Sometimes Blender crashes after changing the driver value.

Probably this requires the updates being called, but the problem with these atm is that calling them gives too much of a slowdown that it's infeasible to do so.
