Create Black, not Alpha
Hello,
I think I’m loosing my mind. I haven’t worked too much with 3d layers in the past. I have a composition with many 3d layers aligned in z-space, and I need to fade many of them to black as they get closer to the floor. however, when i mask a layer’s bottom, it looks black, but that black is acually an alpha channel, so i get transparency. How can I in after effects create a black non-transparent fade on a layer?

Place a fullscreen black solid (2D) at the bottom of the timeline?

This will make me a black backgound, which when rendered would be an alpha channel. This would be ok, but actually I have a background plate that I’m already using. Imagine 3 layers arranged behind each other with the 4th layer being some stock footage. I need to gradient to black the bottom half of layers 1-3. Doing this on the layers with a mask or anything that colors the layer black makes the bottom half of my 3d layers transparent and I can see my background through them, when i really want them to be black.

Steve,
A full screen black “solid” won’t render as an alpha channel. A Black “background” will if you tell it to in render queue. They are different.
Use Steve’s suggestion and parent a black solid to each of your masked layers. This will not be transparent.Good Luck.

At first it sounded like you wanted to fade the layer to black, now it sounds like you want a ramp on the layers. The implementation will change depending on what it is you really want to do, but I would recommend either a Generate > Fill effect using a Black Fill that you can animate the opacity of (for fading to black) or parenting a solid with a Generate > Ramp effect applied set to the Multiply blend mode.

Ahh, the Ramp effect has helped dramatically. That was the ticket. Doh!
Thanks all.
