Is there some way to to block out Chroma Key parts of the screen? For example a nasty lightning part (shadow) which shows up on the web screen. It it possible to put something transparant on top of the Chroma Key?

Dont tell me get better, lightning, i have good lightning, but the green screen behind me have to make a 90degree turn and behind me, i am exactly in that turn which shows in the top right some nasty shadows from the green screen which i cant get removed with Chroma Key setting. Would be easier to put a transparant Chroma Key on top of it, and then it show the underlying layer (background). Or something with a Alpha Channel?

Here is how it's done:
- Open your favorite image editor and create a new image the size of your webcam resolution.
- Fill everything with the color WHITE
- Now, by using a paint brush, paint over the parts of the image that you DON'T want to see with the color BLACK (It might help if you overlay a webcam snapshot, but make sure to remove it before saving)
- Now save the image (png or something like that)
- In OBS open the Filter window for the webcam and under Effect Filters add the "Image Mask/Blend" filter
- By using the arrows, move the new filter above your chroma/color key filter
- in the Image Mask/Blend filter leave everything as is, only select the image you just made by clicking the Browse button.
