How can I calibrate the lens of an engine world camera to match a real one?

Hi!

We are currently working on the set up for live composition in the engine. We have achieved tracking the camera motion via HTC vive motion control, recevie and chroma key live video feed from a real worl camera through a blckmagic destktop lionk caputre card, howevere, we are having some issues reagrding the lens specs matching both real wolrd and engine camera, so the live video feed matches correctly inside the engine.

If any of you have succesfully build the live composition system, i would be really thankfull with all the info you can give me.

thanks in advance :smiley:

Please share if you found a way of doing it.
