VR Tunnelling Pro

Manual (Unity)

Plug-and-Play VR Comfort


Instantly make your Unity or UE4 VR game more comfortable! VR Tunnelling Pro reduces sim-sickness during intense motion with a wide range of industry-leading techniques. From tunnelling - controlling peripheral vision or replacing it with a static "cage" - to altering camera motion, VRTP is a one-stop platform for adding existing techniques and easily developing your own.

Open Source for Unity and UE4


Thanks to support from Oculus, VRTP is now completely free for both Unity and Unreal Engine 4 (currently in beta). A simplified version is included in VR Toolkit for Unity.

Fully Customisable


Use the default settings or delve into the huge range of options and modes, including cubemaps, 3D cage and blur. Mask objects from effects or create static windows and portals. Use the debug tools to fine-tune motion sensitivity.



VRTP for Unity runs on Oculus Rift, Vive, PSVR, Google VR, Gear VR, Oculus Go and even Oculus Quest out of the box. It includes a lightning-fast mobile version and supports single pass stereo.


Unreal Marketplace (coming soon)

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.

Rich API, Intuitive Editors


Tweak anything you want with VRTPs custom editors or use the in-depth documentation to dive into the fully-featured API.

Battle Tested


VRTP is based on the acclaimed comfort solutions developed for our zero-g VR shooter Sublevel Zero Redux.

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.
