Alphas not produced in Animation Sequence

[PabloMack]

When I render a still, TG produces an image and an alpha but when I render an animation sequence it only produces the image files.  Is there a way to turn on production of alpha files?

Thanks

In the Sequence/Output tab of the render node select "Extra output images" and navigate to a directory you want to save the alpha masks to (usually the same directory as the animation files) and your done.

So "Extra Output Images" really means "Alpha Output Images"?  I thought it just meant another place to store a duplicate copy of the same image files. I never would have guessed it. Thank you.

Yes it is the alphas.
