Accidentally made backdrop viewer size zero. How to get it back? I accidentally decreased the size of the viewer in the backdrop to zero. Now it displays as a small cross and I cannot reach the handles to enlarge it again. Does anyone know how to get it back, without needing to rebuild my project?
Open the sidebar in the compositor N
Open the View tab
Increase the Zoom property in the Backdrop panel. Alternatively you can use Fit to fit the background image into the view or Reset Backdrop to reset the offset and zoom.
