Mutiny bacula8630 i swear ive seen somewhere a VR scene where someone plays together with themselves in VR. Found it , it’s a Jav scene from SOD that has Eimi Fukada . here is the link https://www.sexlikereal.com/scenes/eimi-fukada-standoffish-eime-and-doting-eimie-come-at-you-from-both-sides-19112
Great idea 
im actually curious as to what special effects/ techniques can be used to pull things like this off 
Bucket619 Thanks for the reference! I hadn't seen that one.
There are a few ways to tackle it, from precise control of framing/blocking (so the performer doesn't cross over where her double will be) then using a simple matte to combine the two takes, all the way to using greenscreen/difference mattes/other keying tools to layer them. But it's not just about separating them in the frame, you also have to consider depth. If you use a mask to key out one and place them over the other, the effect will break your brain if they're located in the same slice of depth from the lens, or if the one keyed behind the other is actually closer to the lens. Your eyes and your brain will disagree on what's happening and it's deeply unpleasant.
It's a lot to control for, but the challenge sounds like a blast.
Also, check out from around 3:00-3:30 here (and some transitions/effects later in the edit): https://www.sexlikereal.com/scenes/the-future-is-beautiful-a-vr-pmv-29044
I played with the idea of layering/double exposures in this project, but it was achieved with simple blending modes because I wanted to lean into the hologram effect of seeing through the performers.
Mutiny This is actually something I've been thinking a lot about. It's tricky to pull it off and, like you say, would require testing and a lot of planning...but it's totally doable.
I ask for your patience, but...challenge accepted!
Nice! If you could pull it off, I think it would be really cool!

This was my question as well. How does depth affect the split screen? Does the line where the two individual takes join act differently when depth is involved? Will it have a weird effect on the brain?
It will be interesting to see what tests reveal.

I had forgot. But now that you mention it, I do remember someone else mentioning that particular scene to me. Thanks for the link. I’ll definitely take a look.
bacula8630 yea i haven’t watched this one but i remember it. i think i didnt watch it only because it didnt have a script. ill get on later to view the trailer and see what it looks like 
let me know your experience with it as well so i can compare or know what to expect haha
bacula8630 As long as you rotoscope the one closer and put him over the other, you wont have problems with depth.
I’m afraid your technical knowledge exceeds my own.
I know what rotoscoping is. It’s an animation technique used in video by animating frame by frame. Like the famous A-ha video, “Take on Me”.
I’m not exactly sure how it applies here though. I’m curious to learn though.
bacula8630 We also use this word for a technique to cut a person out of an image so its a separate layer, then you can composite that person over another.
Try searching for "rotoscoping mask"
@Sandi_SLR want to ask how effects work in VR as well ? if you could check out in my post “Succubus Prison” , i added in about 5 images showing a transition of a special effect in a Vr scene
https://forum.sexlikereal.com/d/3782-succubus-prison-lewd-demons-scene-idea-that-has-a-part-1-and-2/12 this is the one
bacula8630 Yep! Rotoscoping historically implies doing it by hand (the process of painting out the background manually) but it can refer to the act of cutting out elements in general. Depending on the footage and the tools available there are many different ways to achieve it, like chroma key (greenscreen/bluescreen), depth matte (an algorithm looks at the focus/sharpness to determine an element's distance from the lens...not perfect, but amazing advancement in the last couple years), difference matte (the program compares a "clean plate" — the shot with the background only — to the same shot with the performer in frame and cuts out any pixels that are identical, so only the performer remains...often has issues because of camera sensor noise, background elements moving a little, that kind of thing). There are even tools now like Magic Mask in Davinci Resolve that use machine learning to recognize a body, or even a body part like selecting a face, or hair, or clothes. It's all pretty incredible.
Usually an effective matte requires some combination of tools to get the right polish. You also have to consider things like matching light direction and color temperature.
Then, a final color grade and application of film grain/digital noise can help tie it all together and hide the seams.

Thanks for the info guys!
I was familiar with a lot of the masking techniques you guys mentioned. But I never knew the names for them. But I’m always open to learning new things. So I appreciate you guys taking the time to reply.
Also, sounds like editing software has come a long way in recent years. Many complex masks needed to be hand drawn before. But it sounds like the software takes a lot of the tedium out of those processes. With maybe a little fine tuning here and there.
All very cool stuff! Learn something new everyday!
bacula8630 editing software has come a long way
It's wild, man. We live in the future.
Still waiting for my very own porn holodeck! 
bacula8630 im waiting to save up money for the best option for a sick passthrough VR headset between the options out right now
Mutiny There was a whole episode of THE ORVILLE about this!
Man, if I had a holodeck, my family and friends would probably never see me again! 
Mutiny I'm so torn between getting a Quest Pro now vs waiting for the 3 to come out.
I just bought a Quest Pro a couple months ago. The resolution is the same as the Quest 2. But the optics on the Pro are super impressive! The clarity is probably the best available at the moment.
But since the Quest 3 is pretty close to release. I’d probably wait and see what that’s like before making any final decision.
Mutiny bacula8630 Well for reference i have the Vive Pro 
and have not experienced past the screendoor effect of the higher resolutions
Mutiny Thanks for the reference! I hadn't seen that one.
Lol, right...there's so many, would take a life time to actually go threw every scene in vr
sheesh 
i will youtube this to see what these things look like lol
