Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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.
