Keying right?

#1

Hi!
I’m having a few troubles getting the keying to look the way I want it in combustion4.
I have this image where you see a distant city/village over the horizon, a huge grass land infront of it and then above the city there’s this huge sky with clouds.

Now, I’ve used the diamond keyer to remove the sky with the clouds etc because I want another cloudscape to replace it (a sunset), everything looks great until I get anoyed when the city in the horizon starts to vanish when I key out the sky. Everything looks great, the sky is perfectly gone but some areas of the city in the horizon aswell, now, can I use some specific tool to key out the city alone, select it and then remove all keying on it? I’ve tried the tolerance/softness etc. in the diamond keyer but the sky grows back when I remove keying of the city…

I’m not that good at combustion yet so…hopefully you’ll understand what my problem is :slight_smile:

You can isolate your keying to ignore the city with a poly selection (operators->selection->draw selection). Just draw a polygon selection around your city, and check the invert option (you can animate and track the vertices of the selection if need be). Place this operator right below your keying in the workspace stack, and the keying won’t affect your city.
