[FREE] VR Tunnelling Pro - Plug-And-Play VR Comfort

Trailer
Asset Store

Website

Instantly make your Unity VR game more comfortable! VR Tunnelling Pro (VRTP) reduces sim-sickness during intense motion by reducing peripheral vision and/or replacing it with static "cage" imagery. Tunnelling has been used to great effect in VR games such as Ubisoft's Eagle Flight and in our own zero-g 6DoF shooter Sublevel Zero Redux.

Free and Open Source
With Oculus' support, we've now made VRTP free on the Asset Store and on Github here! We're working on a range of new features and improvements, and are pleased to announce that VRTP will support Oculus Quest alongside all other major platforms from all vendors.

The Github repo includes a dev branch with the latest techniques in beta, plus improvements to the editor GUI and more. Please feel free to submit issues and pull requests on the github, or discuss further here.



Fully Customisable
Use the default settings or delve into the huge range of options and modes, including colour, cubemap, 3D cage and blur. Mask objects from the effect or create static windows and portals. Use the debug tools to fine-tune motion sensitivity. Use Force Vignette mode to take full manual control of tunnelling.

Supports ALL Major VR Platforms
VRTP runs seamlessly on Rift, Vive, PSVR, Go, GearVR, Cardboard, Daydream and now Oculus Quest out of the box, including a lightning-fast mobile version which can also be used on non-mobile when performance is tight. Single-pass stereo is supported on non-mobile platforms, with beta support on mobile.



Powerful Preset System
Create full or partial presets in-editor and apply at runtime with one line of code. Let your players choose the settings that work for them.

Full Source Code, In-Depth Documentation
Get up and running in minutes with the quickstart guide, then drill down with tutorials and the comprehensive manual. Tweak anything you want with full source code and API documentation!

Why VRTP?
Comfort is one of the biggest and most common challenges VR developers face. Sim-sickness can be the difference between a great experience and an unplayable mess, in everything from indie projects to huge budget AAA titles. Tunnelling is a powerful tool for increasing comfort in almost any VR project.

Whether first-person, third-person, vehicular or anything else, we think VR games should put a premium on comprehensive, player-customisable comfort solutions. We've developed VR Tunnelling Pro to expand and improve upon the acclaimed comfort options in Sublevel Zero Redux, and make it easy for anyone to reduce sim-sickness in their own projects.

Unreal Engine 4
VRTP is now also available for UE4 - see the Oculus blog post for more details.

 

Update: VRTP has just launched on the Asset Store!

 

Nice! Would you consider adding an effect like this to the package?

https://www.assetstore.unity3d.com/en/#!/content/61275

If yes, count me in as a customer since it seems it will do all the tunneling effects one could possibly need!

 

Hi! While that's a cool effect, we really want VRTP to have a laser-focus on comfort, and that's more towards immersion in my mind. That said, I see no reason that effect would have any conflicts with VRTP, so they should work well together.

 

Cool thanks! I bought them both

 

Great Let me know if you have any troubles using them together so I can help out.

 

I've purchased this plugin for testing and noticed the radius of the tunneling vignette is coupled to the value of the Unity camera's far clipping plane.

Is there a reason for this, or a workaround? For the application I'm testing on I need the clipping plane to be at at least 2000, but with that value the vignette appears to be always in view even without turning.

 

Oops, sorry! I'll try to get you a workaround ASAP and then update the plugin.

 

Ok, here's a workaround. You'll have to go into VrTunnellingPro/Scripts/TunnellingBase.cs, find line 501 and insert a couple of lines afterwards.

This is the code you're looking for:

#if !UNITY_ANDROID && !UNITY_STANDALONE_OSX

// Reverse y for D3D, PS4, XB1, Metal

var api = SystemInfo.graphicsDeviceType;

if (

    api != UnityEngine.Rendering.GraphicsDeviceType.OpenGLES3 &&

    api != UnityEngine.Rendering.GraphicsDeviceType.OpenGLES2 &&

    api != UnityEngine.Rendering.GraphicsDeviceType.OpenGLCore &&

    api != UnityEngine.Rendering.GraphicsDeviceType.Vulkan

){

    _eyeProjection[0][1, 1] *= -1f;

    _eyeProjection[1][1, 1] *= -1f;

}

#endif

After that, insert the following two lines:

_eyeProjection[0][3, 3] = 0.002f;

_eyeProjection[1][3, 3] = 0.002f;

That should fix the issue. I'll patch this into the Asset Store package ASAP. Thanks for the catch!

 

Does it contain a locomotion controll for vr?

 

No - it's designed to work well with almost any locomotion method so it doesn't include one itself.

 

ah pity, I need a locomotion solution for vr... thanks

 

The patch is now live in the Asset Store package, so you can just update rather than use the workaround.

 

Version 1.1 out! Changelog:

• Beta support for Single Pass Stereo on Mobile
• Fixed a skybox regression bug on Android

 

Can you provide any details on how the mobile version works? The documentation says "without post-processing" which is fine, but I'm wondering about what it is. Are you rendering a piece of custom geometry that only covers the area where the effect is active? I assume you would render the opaque area before the geometry to write out the z-depth, and then do the feathered area as a final blended pass?

Does the mobile version support a stereo cubemap?

Is there any plans to support single pass stereo rendering on mobile? Can you elaborate on what issues you are having with it now? Unity's new lightweight rendering pipeline should support mobile VR shortly and I'm expecting the efficiency improvements will be very useful, but the scriptable render pipelines require single-pass stereo.

Thanks.

 

Really sorry for the huge delay - for some reason I didn't receive any notification about your post.

The mobile version works exactly as you guessed. An iris mesh gets drawn before anything else to zero depth, then a secondary feathered inner iris mesh at the end of the frame.

Stereo cubemap is not yet supported but I'm looking into it at the moment.

Single pass on mobile is currently in beta - it should work in pretty much all cases. The docs are a bit behind on that, sorry!

The asset is not currently tested with LWRP, but that's another thing I'm currently looking into.

Hope that helps, and apologies again for the huge delay.

 

The asset is now free, will you no longer be supporting it?

 

Don't worry - it's actually the complete opposite! I'm about to update the OP, but the gist is - we're now working with Oculus to open source the plugin, add a raft of new features, support even more platforms and even port it to Unreal Engine 4! As the first step, the asset is now free on the store, and it'll be on our github in about a week's time

 

Here's a sneak peek at the improvements we're making to look-and-feel, and some of the new features!

VRTP's UI is getting a whole new look, with lots of quality-of-life tweaks to make it even easier to use in the editor.


We're adding a whole new section of effects, based on modifying motion.


All the new settings will of course be exposed both in the API and in Presets, which are also getting some UI improvements.


We'll have more updates for you shortly, including a date for when VRTP will be open-sourced on our Github!

 

How can we use this with VRTK ?

 

I'll try to put together some best practices on that front.

 

When u plan to put ? are there any estimated time ?

 

Quick announcement - the plugin will be open sourced on our Github this Monday, 8th October!

Hopefully a few days - after we've open sourced on Monday I'll try to look at VRTK best practices.

 

thank you

 

VRTP is now available open-source on our github!

I'm facing some oddities probably related to your plugin.

After days attempting to get a UWP build to work, I was finally able to create a Mixed Reality app via IL2CPP (I won't even try .NET anymore, Microsoft is making it impossible on purpose and it's not worth the hassle).

When I got to test the app, it shows this weird shader issue in front of the player camera. This never appears when testing the game directly on Unity.

That being said, the plugin still works fine and shows the correct tunneling materials when the camera motion goes beyond my defined threshold (and these tunneling materials are alright too). What leads me to believe that this is a VRTunnelling problem is that this halo only appears inversely to the camera motion (aka when your plugin isn't detecting any motion, the halo slowly appears from behind the camera).

Other things that might be screwing up with this could be a HoloKit-specific material that is applied to the camera's Fade in/out plane, or something about the Post-Processing stack that I'm also using. I'll try debugging those tomorrow.

For now, do you have any leads?

 

Got it. For some reason, Iris Z Rejection is causing this issue. Disabling it resolves this issue, but I dunno what difference that makes in the long run.

 

Yes, that's definitely the z-reject iris. Not sure why it's doing that however. Are you on the master branch or dev? Disabling it is fine, but you don't get the fillrate benefit you otherwise would.

 

I see this also and I am trying this on the Oculus Go. I am using mobile version - Not sure if z-reject iris is same issue (look the same) or where I need to go to disable it. Thanks

 

For mobile I recommend grabbing the latest version on the dev branch on GitHub - it should work fine on Go (does for me at least!).

EDIT: Note that there should be an update to the master branch within a month as well.

 

Will try - Thanks

 

Hi guys,

I've just updated the dev branch and this issue should be fixed.

The issue was, the iris mesh uses vertex colors in the vertex shader to shrink the iris, and for some reason under some versions of Unity 2018 the vertex colors were not being passed to the shader. I've moved to using UV coords instead and it should work fine now! Apologies for that taking a while, it was a really weird bug.

 

Not working same issue...

 

Have you tried the dev branch from the github?

 

Will you be adding support for Windows MR?

 

Looking in to it. As yet we've not tested at all on WMR and it may be that it already works, whether that be the image effect script or the mobile-ready script.

 

Hey Lyje!

I tried the dev branch from Github, but am unable to any color/blurring effects for Oculus Go.

From the Quickstart guide, I have tried adding both the Tunneling / TunnelingMobile script to the CenterEyeAnchor of the TrackingSpace of OVRCameraRig. However, no matter the settings I put for the script, I am unable to get any desired effect on the Oculus Go.

For Blur, nothing happens. For Color mode, I get some shader problem similar to a picture shown previously. Would you mind helping me with the Oculus Go integration?

PS: For both Color/Blur, I am able to get the effect when I play from the Unity Editor. However once I build onto Oculus Go, there is no longer any effect.

 

Possible to create color saturation in the plugin?

EDIT: i see that the iris is using a fbx file, am i able to modify the shape & re export?

 

Hi! You must use the TunnellingMobile component on Go - the non-mobile version will not work. This means blur is not available on Go I'm afraid. When you're having issues with Color mode, is that with the mobile or non-mobile version?

 

It would be possible to add a saturation mode to the non-mobile version, yes, however doubt it will be effective as our peripheral vision has less colour acuity anyway.

It's possible to edit the iris if you'd like, but it's configured very specifically for the effect. Have a look at VertexUtils.cginc IIRC to see how the mesh is used.

 

The Asset Store and Github versions have both just been updated with lots of new features, optimisations and more! We've also just released VRTP for Unreal Engine 4 in beta - check out the Oculus blog post for more details!

Is the last update compatible with LWRP? Thanks

 

Not explicitly. The mobile version should work fine, however the non-mobile version does not yet. SRP support is the next thing we'll be looking at adding, although I would stress we don't have a timeline on that.

EDIT: To clarify, it's perfectly possible to use the mobile version on non-mobile platforms regardless!

 

Thanks, I will test it.

 

Hey, would it be possible to add single pass instanced (multi-view) support?

 

It should work ok with instanced - are you experiencing issues?

 

Hm, can't seem to get it to work with Single Pass Instanced stereo mode. I get an all white screen.

Edit: Using Unity version 2018.2.17f1, if it matters

 

I'll give it a look, thanks for reporting

 

I am not sure if I am totally missing something but everything works fine when not in VR. Once I enable VR the tunneling does not work, using the vive, but mobile tunneling does seem to work. Not sure what is going on.

 

Are you using LWRP or HDRP? What version of Unity are you on?
