Alpha Passthrough. How does it work?

petermc

I’m not a passthrough guy at all but that alpha passthrough scene was infinitely more watchable as a non-passthrough scene than those horrible green screen scenes.

SchnuppiLilac ..alpha mode (A in a white circle)

I just can't seem to find this feature, I tried adding '_ALPHA' to the filename but it didn't work. (DeoVR version 13.9.2)

kurtis316 When you stream the video, you should find the (A) button next to the passthrough on/off toggle in the right-hand passthrough controls panel.

Since you mentioned changing file names: If the (A) button does not appear when playing the downloaded video, then I am stumped.

There should be a pass through icon on the player, you just gotta turn it on and the alpha should be set already.

Vrsumo2017 didnt work for me either

The thing is when I leave it as it is, the passthrough doesn't effect only the background but expands beyond boundaries and permeates her body too, resulting in a transparent appearance. Is this suppose to happen?

Here's a recorded vid that explains the situation https://www.udrop.com/file/8aVm/2023-05-21_16-45-31.mkv

kurtis316 then u might have to manually put the pass through #s in...

Hit that eye icon on the player like you did to turn it on, and to the right in the option hit that eye icon to get to the "pass through" settings.

Going down try putting these #s in order by moving the sliders
50
100
100
550-590 move this slider around there
1000

But streaming for me the alpha automatically works. You downloading the file?

SchnuppiLilac

Seems to be working for streaming only

kurtis316

Yeah, I only watch downloaded files instead of streaming directly from the app, due to limitations in my internet speed, so that's not really an option for me. And yeah, alpha passthrough won't be an option either in that case.

@doublevr @Sandi_SLR can you confirm or deny anything? Are there any plans for a future fix?

SchnuppiLilac

kurtis316 Saw a post in another thread suggesting that a temporary fix could be copying the file onto the Q2 hard drive instead of using DLNA.

Sandi_SLR

kurtis316 Hey, we have an issue with downloads naming, it should include alpha in the name, we will fix it.
In the meantime you can add it yourself by renaming the filename and adding "_alpha".

kurtis316

SchnuppiLilac I tried it out, and I'm happy to say it's working! It's unbelievable that I went through all the other solutions except for this one lol. I finally noticed the "A" button right next to the Passthrough toggle, and now everything is functioning perfectly. Really appreciate your help, man. Thanks !

Hi 👋

I have a question
I'll use this scene as an example
https://www.sexlikereal.com/scenes/banderas-is-banging-14072

My question is, if they film a scene similar to that how the background looks will they be able to add alpha channel to it and will that help the pass through options work better as we manually set the pt options our selves? Or would yall be able to add a preset alpha setting? Or both lol

And I see previous green screen scenes are gonna get re edited with the alpha

Could yall add an alpha channel to that scene i linked or to any other scenes non green screen.
Was just curious 🤔

kurtis316

Sandi_SLR Hey, thanks for the answer. However, I mentioned in a previous post that I have already tried that but it didn't work. Just to give you an an overview of this thread, the issue is related to the readability of alpha files when streamed via DLNA. Somehow, DeoVR doesn't recognize these files as alpha passthrough files (even after renaming them).

For now, we have two potential temporary solutions. The first solution is to directly stream the files from SLR. The second option is to download the file and manually transfer it to the storage of the headset device. So, a permanent fix is still required for the DLNA streaming issue.

Sandi_SLR

Vrsumo2017 Hey, yes we will be able to convert normal (not greenscreen) videos to passthrough with background removal tricks using AI, this was mentioned a few times and there is a thread about it too.

Vrsumo2017

Sandi_SLR this was mentioned a few times and there is a thread about it too

Yes, I remember reading something like that, any idea when these features will be rolling out, for example when will we see a non green screen scene have these alpha channels?

& Thanks for the reply 👍

Vrsumo2017

Sandi_SLR and there is a thread about it

Can I kindly suggest this thread be pinned, I sometimes search for those threads so I can read back what was mentioned about pass through and what is planned, but there's so many discussions.

Idk, just a suggestion ✌️

Sandi_SLR

kurtis316 Aha, we will check what goes wrong.

BursVR

Sandi_SLR A few months later, have you guys checked what's wrong with playing alpha videos via DLNA?
Copying 30-40 GB to my headset is not really a solution or workaround for me, and not something I plan to do often.
What's the point of using DLNA then for these types of videos? From my dev point of view, it shouldn't be difficult to debug.

BursVR
Some DLNA servers essentially 'rename' the video went sent over streaming like plex.
I believe Kodi doesnt so give that one a try

BursVR

kudirnad Actually, I'm streaming from Windows 11's built-in DLNA server. I'll give Kodi a try. Haven't used it in years LoL 🙂

BursVR

kudirnad I've just tried it with Kodi. Thanks for the suggestion, but it's all the same. I wouldn't say it has anything to do with DLNA itself, but the way DeoVR is handling alpha passthrough streams via DLNA.
