Is there an easier way to make black transparent when blending?

Hi,
I’m working on a fire effect, and I’m using three Ellipses that are being deformed by noise, but I want the background to be transparent. If I connect the Out of an ellipse to the Master, it’s transparent, but after blending the three shapes together, the background is black, and I have to use a Color Mask + Invert to get the correct Alpha.

If I connect the Multiply Out of one of the shapes, I get nothing in the preview. The same happens if I connect Blend Out. Why is that? Doesn’t it have an alpha channel?

Is there a more efficient / simpler way to do this? :slight_smile:

Oops, my bad. The color nodes for the Ellipse was set to 0% alpha. Kind of confusing that the Multiply nodes still showed it with color :slight_smile:
