Hi Magic Leap! I was hoping to get your opinion on some issue we are having when recording footage when we configure the camera to have an alpha override of 1. I suppose it's easiest to explain if you see it in a video, here you will see footage of ML2 followed by footage of Hololens 2 also record…

This is the biggest problem we have, I want to replace my HL2 it's a dinosaur! help me out :slight_smile:

Hi @javier Apologies for the delay, I'm on it. I'll report back asap.

Hi @javier I spoke with our engineers. ML2 in this case was inferring alpha from color/depth. What's happening is "alpha boost," where everything above a threshold is considered to have a fixed alpha. We are working to resolve this issue but it won't be in the next release this month. In the meantim…

Hi @kdowney ! thanks for helping out. Though I'm not sure I follow what you mean by "send the alpha via Unity". The alpha is properly set on the shaders, as you can see it works correctly in other platforms. Is there anything else I can do specifically for ML 2? I was under the impression that the …

Thanks for following up @javier . I talked with our graphics engineers and the idea was basically sending the alpha via Unity by either upgrading the project to 2022.2.12f1+ or through URP post-processing effects to directly control the alpha output of the final frame. Our team noted we're working t…

I did update to 2022.2.14 but the issue remains, unless I have to initiate capture through code? I'm doing it with the built in camera function from the OS. I can't change to URP, though if there's a way to fix this before the proper fix comes in summer it would be amazing.

One other thing our team noticed: With an alpha override of 1, those dark halos would be fully expected if there is even a little non-zero color around those white orbs. Not sure if that's intended, but if it isn't then you may also address the issue by ensuring there isn't any extra content around …

I guess I just don't understand what's going on behind the scenes, I don't even understand why footage is translucent to begin with and I don't understand why there needs to be an alpha override either. From my point of view, I render things with the proper color, alpha and depth, so I would expect…

@javier This appears to be a depth writing or depth test issue. Our 3rd eye camera records opaque objects even if they appear transparent in the headset. One solution is to render the areas not effects by the shadow as transparent. To accomplish this edit lines 100 -109 to set the ZWrite to Off and…
