Sorry for the late reply. The saved file should open. Now the file may be a blank image, though. I wasn't able to get the action that copies from the canvas to be reliable all the time.
On another note the load texture from canvas action only loads what's on screen. Or should if it's working
Aah, that might be the problem then.. is there any way I could use this to take a screenshot of the whole layout? I'm trying to map my game and the default screenshot function in C2 doesn't do that, I was hoping this did.
