Rendering From Matinee With Alpha Channel

Hey all,

I’m trying to figure out if there is a better way to render out scenes from matinee to composite with.

Here’s an example: I have a landscape scene with foreground grass and flowers and then in the background the sky and mountains. What I do is seperate these two elements and sandwich composite video in between them in post production.

What I’ve been doing since UDK is using a plane of solid color to key out in After Effects to allow me to seperate foreground and background elements. I’m wondering if there is a better way - a way to render out the transparency without the hacky need to place a faux greenscreen in the scene.

If not. It would be a nice feature.

Render Custom Depth is already working for screenshots.

Is there any way to make that work with matinee?

Any news on this? +1 for being able to render an alpha out of Unreal.

Still want this killer feature.

This is badly needed. I would love the option to simply run the highresscreenshot command for each frame. Then we would get all the buffer targets. Please unreal make this a reality. its the only thing holding unreal back from being a VFX and compositing tool.

It’s so obvious.

Composting is such a pain without it.
