Question / Help Cropping Webcam Video [Non-Rectangular!]

[Iroh]

Hello OBS Forum,

I'm trying to crop my webcam to fit inside a frame I made in the style of the game don't starve, the frame is below.

Unfortunately no square crop will fit my webcam in this frame. How can I mask out my webcam such that it fills but does not expand beyond this frame?

Thanks,

- Nate
