I have a kinect TOP using player index. I remove the black from the image using a chroma key with a minimum value between 0 and .1. I was testing it using the Kinect Recorder tool and it worked exactly as intended - leaving a gray player and a transparent background. But now when I use the live kinect feed for player index, I’m never able to remove the black background using chroma key. I compared the recorded kinect top to the live top via a chop and they looked identical (~.1 values across rgb, no alpha).
It might work better if you switch the Pixel Format of chroma1 to 8-bit Fixed (RGBA) on the Common page.
The Player Index of the of the Kinect Azure is just a mono greyscale image, and the chroma defaults to matching the same as its input which means there isn’t an alpha channel.
You could also switch the the RGB Output on chroma1 to be ‘New Alpha’ which leave the texture as mono greyscale image, but you’ll have the correct key value.
