I want all my shadows to look like they’re coming from a single light source. As far as I can tell, TB doesn’t let me manipulate the shadow values, so I can’t recreate the dimensions in a new shadow. Next version should allow me to do this.
I see a way to get this done. The first one would be to simply drop both of your elements inside the same shadow effect. This way when you change the shadow it will affect it for all the element that are attached to it.
This isn’t perfect but it could do the trick. I made a feature request for being able to actually duplicate an effect instead of only cloning (a clone would have the same effect as if you dropped the element in the under the same shadow) that would allow much greater flexibilities.
