Re installed alxr and that fixed that. Works! However are the edges around figures suspose to be grainy ? Is kinda low resolution unless thats normal. I do have green screen working but its low res in ghost mode and green screen.
The reason why the Quest 2 "real view" (or see-through) is grainy is because it's a composite image generated from 4 images recorded by the 4 IR cameras.
Long story short, an IR camera is NOT a regular camera as it doesn't read and record all colors. It reads and analyses infrared colors (the meaning of IR).
This is why, in that mode, you'll see a blinking dot on some devices like your phone/tablets or even a power bar. Those blinking dots are the visual representation of the generated infrared radiation generated by a signal sent by the device antenna. (If you watched movies or real footage of soldiers in warzone which has a blinking dot on their position like in CoD games where you're in a plane with big guns, that's the principle behind the blinking dot.)
If you look at any active screen (like a TV), even if it's displaying really dark colors, it will look pure white if its RGB cell are not shut down. This is because IR is not necessary color oriented (though color does affect how much light is reflected off a surface, hence dark and light colors not simulated may appears as properly dark or light.)
Each camera on the Quest 2 generate an IR data image in 640x480 resolution. This is to allow good general tracking of the environment without wasting a lot of CPU and battery charge on the recording. So you can't exceed that 640x480 resolution per camera, in quality, on the Quest 2 without some custom setup that includes an additional external camera and a special overlay app. Also, because it's IR and that's basically an uncontrollable variant in the environment as light from light bulbs aren't persistant, but flickering based on their Amps, that's another reason for the grainy fluctuation from the pass-through. Dropping the light low, but high enough for the headset to still detects thing reduces the chances for the light bulbs to generate high density IR which generate the lighter and more noticeable white pixels from high density IR rays.
With the Quest Pro, it's actually a single additional 8MB camera that generate the color view (which explain why going in AR mode drains the Quest Pro battery so much faster.) This is also why it's slightly deformed.
As for the color of the background, while green is a well known color that can easily be extracted, I would suggest, in this case, to check colors in the blue or red spectrum. Here's a link that explain the impossible colors :
https://en.wikipedia.org/wiki/Impossible_color
Green screen comes from that concept where certain shade of green is impossible to get in reality in normal situation, hence going for the color closest to it allows you to avoid stuff in reality from being removed. Hence it's possible to have extreme blue and red shades as well that aren't present in the rendered image. This would remove the green outline generating by the cropping and replace it with a blue or red color. (If you get the right red color, it could even make the outline of the character a tad bit smooth instead of cut-out.)
