I have noticed that when I save to Tiff and check ‘store alpha channel’, the alpha channel is often missing.
I can’t always replicate the issue so it’s difficult to find the cause. When I go back through the settings, all the images have ‘store alpha channel’ box still checked except for the first one, which has mysteriously unchecked itself.
To add to the confusion, on the occasions when an image does save the alpha channel, sometimes none of the render elements have the alpha channel saved.
Like I said, it happens at random. Sometimes I hit render and it all works. Sometimes I hit render again (same image, same project) and it doesn’t work.
I was wonder whether anyone else has this issue and if there was a solution?
Thanks
