Preference or Panel Option for frame animation to start at from zero (0)
When working with frame based animations in Photoshop the frame numbers start at 1.
This is fine for most things, like making an animated gif for export, but when intending to export the individual frames sometimes there is a need to have the frame numbers start at 0.
For instance when animating frames to be imported into another app which is more programmer orented, where numbered systems start at 0 (video game engines, etc), or even After Effects, which starts at frame 0.
If you ever need to come back in and make changes to the Photoshop file you have to “remember to subtract one.. or was that add one? no I was right the first time”.
