VR news – Resolving a few issues with new Oculus drivers V0.7.0.0-BETA

We are having a few issues with the latest Oculus drivers (V0.7.0.0-BETA).

Current available VR Experience 4 Oculus Rift and our Quantic Rift demo are not working any more with new driver and V0.6 driver version is required.

We won’t thank Oculus for this non-backward-compatible change and we won’t thank them also for not upgrading MacOSX version of Oculus drivers (still in V0.5) as source are now diverging between OS X and Windows versions.

The new thing is that only one camera needs to be defined into our scene to have VR stuff which breaks all that was done before.

So we had to make several changes inside our code to make it work and a new version of VR Experience 4 Oculus Rift is almost ready and will be available very soon.
But good news: performances are a lot increased !

The Quantic Rift demo is a bit more broken because of it’s integration with UFPS engine, but as it is currently ported to the Unreal Engine 4 that’s not a big problem.

Note that if you have a NVIDIA graphic card, with the new Oculus drivers version under Windows 10 it is required to use the latest (beta) drivers from NVIDIA as recommended by Oculus (check Oculus page for details).

Unity vs Unreal: Quantic Rift 3D engine selection


SebL ported a subset of Quantic Rift’s first scene to Unreal 3D engine and the visual result is really quite impressive and the first performances results are quite good, even in VR.

So we are now trying to create the same scene as the one we made under Unity but with Unreal engine to be able to select the best engine for our full FPS game.

That means not even porting all 3D scene but also porting all C# scripts that we have already achieve or integrated to blueprints or C++ code (FPS engine, lift animation, characters animation, destruction of objects, VR cam management…).

This is really not an easy task and we don’t really know, how long it will take as we are more used to Unity Engine but we want to know what we can get with that engine before creating the full game.

VR Experience v2.0 has been released for iOS and Android.

Here is the cool new features list in response to various users’ wishes:
– VR drift fixed

VR0: magnet toggle: move on/off
VR1: magnet toggle: next scene, look down; move on/off
VR2: magnet toggle: move on/off, look down; next scene
VR3: look down; move on/off
– Configurable player height
– Configurable player speed
– Configurable player eyes distance
– Digital Pad controller when in “Normal” mode (left/right/forward/backward/rot left/rot right) [replaces long tap action]
– Performances improved on some levels


[update: 2.1 android: now 100% compatible with Durovis Dive 7 VR helmet for 7″ tablets such as the Nexus 7]


Homido vs Durovis Dive VR headsets comparison

The ideoservo team tried both the Homido and Durovis Dive 5 VR headsets at Laval Virtual 2015. These VR helmets are used with smartphones and do not compete directly with the Oculus Rift VR headset.

Compared to the Google Cardboard (less than 20 euros), both are good premium manufactured VR helmets (60 to 70 euros).

We have a little preference for the Homido (French/Chinese design), because we found that it had better VR feeling when we tried both at the exhibit (lenses can be adjusted in depth and in lateral distance which is really a great idea).  It is also shipped with an optional bluetooth controller (making the magnet useless ?). It would have been a good idea to also ship a magnet for compatibility with magnet enabled apps (such as VR Experience) – hopefully we had one in our pocket thanks to… Durovis !

The Durovis Dive 5 (German design) is now shipped with a nice designed magnet toggle and the Leap Motion system can also be added (we did not try it at the exhibit). It is also 10 euros less than the Homido helmet. Lenses can also be adjusted in depth and in lateral distance for better VR comfort.

A Durovis Dive 7 for small tablets (Nexus 7 …) is also available (a bit expensive as it is 115 euros at the moment) but it really looks great (we have also ordered one and it will be supported by our apps).


At the moment our application “VR Experience” needs a magnet to toggle start/stop walking (so we can say that the Durovis Dive 5 is maybe better supported).

You can buy one of those helmets on their official pages (please click on the images above).

Microsoft Hololens: augmented reality headset

After the Oculus Rift headset, Google glasses, the Sony Morpheus project, the Samsung Gear VR, the Google cardboard, it’s now time for Microsoft to build a VR headset, as they say, Microsoft HoloLens goes beyond augmented reality and virtual reality by enabling you to interact with three-dimensional holograms blended with your real world.
