So I had this same issue with the Ricoh Theta V and just recently found a band-aid solution that seems to work for now until someone finds something better.
I looked around and started running through various Unity versions even ones that had been previously confirmed to work but they all gave that same pins error. I finally tried uninstalling the recommended UVC drivers that have been linked above and instead installing older drivers that @craig inked in this post:
If you do this make sure to uninstall the recommended drivers or it won’t work. Then in Unity instead of trying to read the Ricoh Theta V/Z1 FullHD or Ricoh Theta V/Z1 4k streams, you will read the Ricoh Theta V FullHD or Ricoh Theta V 4k streams.
My current setup:
Using the skybox method
Unity 2020.2.4f1 (though I think I tested it on earlier versions and it also works)
Ricoh Theta V
Firmware Version: 3.50.1
Microsoft Windows 10 Education
(First time posting here so let me know if there is anything else that I should add)
Oh sure yeah! I used a skybox, here was the basic script I used:
using UnityEngine;
public class getRicohStream : MonoBehaviour
{
static WebCamTexture ricohStream;
string camName = "RICOH THETA V FullHD"; // Name of your camera.
public Material camMaterial; // Skybox material
void Start()
{
WebCamDevice[] devices = WebCamTexture.devices;
//printing out all video sources for debugging purposes
Debug.Log("Number of web cams connected: " + devices.Length);
for (int i = 0; i < devices.Length; i++)
{
Debug.Log(i + " " + devices[i].name);
}
if (ricohStream == null)
ricohStream = new WebCamTexture(camName, 3840, 1920); // Resolution you want
if (!ricohStream.isPlaying)
ricohStream.Play();
if (camMaterial != null)
camMaterial.mainTexture = ricohStream;
}
}
Then just attach a skybox/panoramic material to camMaterial and use that same material for your skybox.

Hey. Thank you for all the information.
I recently got both the theta v and theta z1. I installed both z1 as well as the v drivers from the links. Both cameras seems to be working in OBS, however in unity, only the theta v is working. The z1 is giving the error “Could not connect pins - RenderStream()”.
With theta v, i’m trying to connect to the camera named “Ricoh Theta V FullHD” and it is working. With theta z1, i’m trying to connect to the camera named “Ricoh Theta V/Z1 FullHD” and that is not working.
Firmware installed is the latest 3.60.1
Unity Version 2020.3.5f1
Windows 10 Build Version 20H2 build 19042.928
Hey. Thank you for the prompt response. As instructed in the video, I uninstalled the version 2 of the drivers and installed the v1.0.0 for the Z1. It is still working in OBS, however in unity, it is now giving a new error “ERROR - Could not find specified video device” when trying to connect to “RICOH THETA Z1 FullHD”.
Got it to work!!! Had to add the DevicePath “foo:bar” key to the registry. Thanks a lot for the help…
For future reference of others, here is a step by step guide:
Uninstall the v2 V/Z1 drivers and install the v1 drivers for Z1 from here.
Open the windows registry and navigate to Computer\HKEY_CLASSES_ROOT\CLSID{860BB310-5D01-11d0-BD3B-00A0C911CE86}\Instance
In the sub items, search for the entry of RICOH THETA Z1 FullHD and 4K. In both those entries, right click and select new → string value.
Name the key “DevicePath”. After naming it, double click it to get a popup for inserting value. Give it a value of “foo:bar” (I think it could be anything really).
That should be enough for Z1 to be recognized by unity. For theta V, the v1 drivers seems to make the registry entries automatically so it should work immediately after installing the drivers.
@nikunjarora12345 thanks for posting the improved solution. I must have installed a different driver on my system that set the registry for me. When I made the video, I mistakenly thought that Z1 driver 1.0.0 would set everything up automatically.
It’s also possible that I set the registry manually when I was trying to get it to work and then I forgot about it.
Thanks again for your contribution to the community knowledge. That original registry hack was from @zimmermegan a while back and other people have improved the technique over time.
I added your solution to the description on the video and added a link to your post.
yea, it’s cool. @Justin originally solved the problem with an older driver. @RicoB also posted some solutions, including skybox. There’s really more contributions. As I normally don’t use Unity, I am just an aggregator. I need to figure out an easier way to provide attribution.
@jcasman , if you have time, please send the video link out to some Unity development groups. It’s fun to use streaming video from the Z1 / V and not so difficult if you use the right driver and setup. However, it’s super difficult if you don’t know to use the right driver and registry modification.
I think the THETA V/Z1 might be the best camera for this type of development at a reasonable equipment cost.
Has there been an updated solution to this form since UVC 3.0 driver came out? Using the UVC 1.0 drivers and 2.0 drivers I still can’t get my Ricoh Theta z1 camera linked up to unity. I have tried just about everything. I am trying to retrieve live video from the z1 onto unity and attach it to a sphere to use it for VR. Any help would be appreciated, I’ve watched about every video online relating to this topic.
As of 2023 Dec 8, I had to use OBS as a virtual camera, then use the virtual camera in Unity. I didn’t try to get it working with the RICOH THETA UVC for that long. I used Windows 10 in my test.
I did some additional tests with the RICOH THETA Z1 and Unity to check the smoothness of the video inside of Unity. This is how it looks with a moving video.
I have the Z1 on a small tripod with an extension. I have a laptop showing a video in front of the camera.
Thank you so much for the help, using the live video feed from a virtual camera through OBS rather than pulling the live video feed directly from the camera allowed unity to work.
Hi, I’m working with @Caleb_Amadoro and am wondering how to wirelessly connect the Ricoh Theta Z1 to the OBS Virtual Camera and if there’s any way to do so? We were successful in connecting the Ricoh Theta Z1 to OBS’s virtual camera and streaming it to Unity, but that was with connecting the Ricoh Theta Z1 to our laptop with a USB C to USB A cable when our goal is to connect it wirelessly. I have found a plug in guide for connecting the Ricoh Theta Z1 to a YouTube live stream but not OBS which is what we need to connect to so that the virtual camera can connect to Unity. Our final goal is as low latency as possible so not using Youtube or any live streaming platform would be best.
