There's this overnight render currently going on. While I was searching for something at my desk I did touch the keyboard and now there's the alpha-view rendering... ??? What can I do to go back to the normal render view? And if the render is finished will I be able to retrieve the normal image? :-[
Edit: Never mind, I found it. I must have touched the [9] on the numeric field; pushing it toggles the view. :D
you've pressed the "a" key, just press it again to toggle back to full colour. You can view RGB outputs the same way via the r, g, and b keys.
Thank you, Kevin! That works as well!
