Question about Kinect

Hey guys!

I’m currently working on a game using Kinect v2 and I need some help to align the Color and Depth cameras so I can create a black background despite of the environment it’s been playing on, only showing the player, each one has a different resolution (1920x1080/512x424) and as far as I can tell, they are in different places, which is why the image won’t align automatically, how can I do this in the engine? It doesn’t even has to be perfect, just better than right now (see on image attached).

I’m displaying this image to a plane, this is the material that shows it:

Lastly, this must be made using Kinect cameras due to the fact that I’m using a Kinect-based plugin.

Thanks in advance for any help!
