Hey guys!
I've made my 1st VR looping video rendered with Daz Studio. 180 degrees stereoscopic (Top / Down).
4K x 4K x 15 FPS (warning: this might be too much for your VR device - though you could re-encode it to a lower resolution).
This is an iRay recreation of the city night stage from my arcade racer Super Night Riders - using assets from the actual game.
I've tested this video using Skybox VR on a Steam VR Windows PC with a Valve Index. Looks great!
Here's the video: dropbox.com/s/2r3ox89nc5vespv/159_180TD_15.mp4?dl=1
Please give it a try and leave your thoughts. Thanks !

If you have a decent enough system you can use your vr googles to see stuff in realtime via unreal or unity. Nice night time city scape,
Works fine on my Oculus Quest 2. Not the crispest image it's ever shown. The road framerate isn't the smoothest and the lamp posts 'pop up' a bit but it definitely works.
Tested on an Oculus Quest 2 via Skybox VR on a wireless virtual desktop connection over WiFi.
Thanks everyone for the feedback!
@Haruchai: The framerate should be smooth enough, you can preview the video on your PC in a 2D video player to have a feel of it.
I think that Skybox VR struggle when it comes to very high resolution videos like this one.
I've actually setup this video to the max that my VR PC can handle (Intel i7 gen 4 + NVidia GTX 1650) which is 4K x 4K x 15 FPS. You could try to re-encode it to 2K and I'm sure it will be much smoother on your Quest!
Yeah, I had already previewed it :) I have copied it directly to the Quest 2 internal memory but haven't been able to open it yet with anything other than Skybox with the same result. I'll try again later via link cable. PC spec is not the issue, Intel i9900, 32GBs of RAM and NVidia RTX 2080 TI .
I see. Thanks!
Here's a new render with a character added: dropbox.com/s/oxkctjsocwscnhf/161_180TB1x2_1.mp4?dl=1
This time it's not an animation but I still have rendered it to a video to be playable in the usual softwares.
It's also at a higher resolution: 4K x 8K x 1 FPS, but the performance shouln't be a problem this time due to the lower FPS.
Any thoughts?
Not sure what was used in the encoding of this one but but nothing on my computer will play it, not even in normal media players as a preveiw.
@Haruchai: That's weird, I can play it in 2D just fine though it takes a few seconds to start displaying something. Maybe the resolution is too much? 4096x8192, the codec is just standard H264.
@Stonemason: No idea, I've just tried 180d as I'm only interested in scenes with a central point of focus. Also 180d allows to have double the resolution for the same performance / size.
Yes weird, tried it in VLC, Windows Media Player, DVD FAB Player and Deo VR. None of them will play it. I'm guessing it's a codec issue. DVD Fab Player did report a codec error, the others just do nothing or shut down.
I successfully rendered full 360 stereo images for VR. You can find an example on my blog: https://www.panotwins.de/spherical-panoramas/stereo/black-vs-white/
To see the stereo version you need a VR headset. Otherwise it falls back to a simple 360 degree panorama.
The panorama was rendered in Iray from two 360° cameras. To set them up just add two new cameras and use the following Lens properties for the left eye:
Lens Distortion Type: spherical
Lens Stereo Offest (mm): -30
Lens properties for the right eye:
Lens Distortion Type: spherical
Lens Stereo Offest (mm): 30
I usually also set these Dimension properties on both cameras:
Use Local Dimensions: On
Aspect Ratio: W 2; H 1
Ive been doing vr images with the 360 degree method of 2 cameras with the stereo offset. what I would like to know, OP, how did u get a 180 dgree image?
I actually render 360 degrees images in Daz Studio, then crop the result keeping only the center of the image - half width - to have 180 degrees images.
Could you provide any more detailed settings for camera(s) /lens / render? I would love to try this but honeslty not sure where to start. Thanks :)
Probably a dead thread but after much tinkering I got a VR180 rig setup that works really well. I have two spherical cameras offset 63mm from one another (Average Pupillary Distance). I also included an Iray Section Plane carfully placed so it cuts off the rear half of the 360 sphere. That way it is only rendering the front half which allows me to render at a higher resolution... Well it still does render the back half but since its all black its almost instant. Currently I have the overall resolution set to 6000w x 3000h... so once rendered I get have my two images that I take in and crop/combine in something like GIMP or Photoshop. With my Nvidia RTX 3090 it's taking about 8 hours each left/right image.
I've been playing around with a VR Rig setup. The way I have it setup that works the best for me, is I have a Camera Group, with a Left and Right Camera. I have the Left X at -2.5cm with a Lens Spherical Offset of -15. I have the Right X at 2.5cm with a Lens Spherical Offset of 15. This seems to give me the best results. I also include a regular camera in the rig to get a better view of what the VR Rig is looking at. You want the subject of the scene to be right in front, unless your intention is that the subject is sitting next to you or something. I've also found that it helps to render the background separately. So, if I have a scene in a living room, with the subject standing in front of a couch, I'll render everything but the subject and the couch first. Then I'll render the subject and the couch for each frame, that way the subject is casting shadows on the couch (I have draw ground on, so there is a shadow on the floor. This approach also means you need to have the subject standing on a flat surface). This approach also means experimenting with lighting to make sure it looks like the subject and couch's lighting match the background.
I tried your X & lense spherical offset settings and it does look alot better! Thank you :)
I'm not aware of any fix to that problem. Many people seem not to notice. I'm not sure whether their 3D depth perception is poor, or they are fooling themselves into thinking it is working, because it doesn't look flat. The store even sells an anaglyph product that purports to create 360 stereo images, but even the store product has the problem. I haven't tried creating 360 stereo in Daz Studio lately, though.
I am not aware of the described problem. In any direction you can see the correct 3D impression.

I think it is crucial not to move the camera itself, but instead use the Lens Stereo Offset parameter of the spherical camera!
I a lot of guys flying Drones showed me a trick for panomra and 360 domes. that if you don't have a paIr of VR goggles you can buy a box for your phone or make your own with Google Cardboard app https://play.google.com/store/apps/details?id=com.google.samples.apps.cardboarddemo&hl=en_US and use the free google vr app. https://arvr.google.com/cardboard/
Also you do not really need the VR goggle to use the google vr 360 app on your mobil device or w10 PC
Edited
do it your self instructions https://arvr.google.com/cardboard/get-cardboard/
Maybe Daz or NVIDIA have fixed something. I haven't seen anything mentioned in the forum or the release highlight threads about a fix. As I mentioned, I haven't tried if for a long time because of the depth inversion problems.The settings you showed are the settings I have always used. I'm going to try again. Thanks for sharing your experience.
I created a new spherical 360 image pair in DS 4.21.1.41 Public Build (aka Beta). Yes, I do believe something has been fixed in the pipeline, be it Daz Studio, Iray version, driver version, or something. I apologize to @StoneMason for posting put of date information in my response. Here is my experiment. It looks good to me, although I didn't view it with a VR headset. I looked at the anaglyph with a GoPro VR viewer app on my computer. I created this image by rendering the two stereographic images (-30 and +30) in Daz Studio and creating the stereo image with StereoPhoto Maker. I did not use the anaglyph product in the store. I don't know if it would work better now or not. If you look at the old examples posted in the commercial thread, you can see the bad stereo inversion as you rotate around and up and down. It was really disconcerting to me, enough so to prevent me from purchasing it.
I checked your panorama on my VR head set. No problems to see there, too.
I published my example also on my website. This was back in December of 2019. I do not know which version of DAZ I used, but the fix would have been bofore that.
That's a long time ago! I don't remember when I last attempted it or what version I was using then either. I've been at the Daz stuff a long time. I noticed a vertical seam in your image. What caused that, do you know? Did you see a seam in mine?
I did not see any vertical seams. Neither in your render, nor in mine. I checked both in a Quest 1. Did not try any other devices.
Good. I had to create an anaglyph from yours to view it in 360 stereo, because I don't have a VR viewer. Maybe it was my conversion that created a seam.
