  • Best performance for forest scenes in VR I was hoping of adding a larger forest multiplayer map to our game. I did some tests, downloaded the free speedtree from untity asset store, a basic terrain, a mixed mode directional light and painted a few trees. Got maybe 45 fps because of too many s...
  • VRTK: how to wait for a headset to be plugged in Hi,

    I'm using VRTK and everything seems to work fine as long as a headset is plugged before I launch the application, but I would like to cover the case where it is not, and would like to display a message while the device is not connected.

    Fo the moment, I see no event when a headset is plugged in, and even after a while, I see a black screen and that's all.

    Any idea where I should look getting events?

    Cheers,

  • Depth/world position reprojection Hello everyone.
    I'm building a raymarching shader. It's working well but I'm still looking to optimise its VR usage. I have read about calculating the depth once for a middle eye, reprojecting it to both eyes, and doing the rest of the shading afterwards. I thought I could also use world position since its also computed by the raymarcher.
    My context is already set up : a first pass render the worldPos to a square render texture. The second shader pass should reproject world pos and compute...

  • How could we access depth texture from device camera? For doing AR I would like to access depth texture to run a computer vision, calculate depth of the things in scene. Which ARCore was not really utilize it

    Are there any API or anyway I could access depth texture? It should be possible from android and iOS with stereo camera yet I can't find any available information about it in unity
  • Setting the ImageTarget name as a variable? Hi, I have a slight problem that is driving me mad. What I want to do is to get the name of the currently tracked ImageTarget set to a variable so I can call it from a function.

  • Two Handed Weapons Hi, so I'm trying to create a sniper rifle in virtual reality, and ideally I would like it to be so that one hand would hold on to the trigger area of the rifle, and the other hand would hold the barrel of the rifle, like how you would hold a sniper rifle in real life. Using VRTK however, I can't seem to find a way to hold on object with both hands at the same time. Does anyone know how to accomplish this, with or without VRTK? Thanks.
  • “App not installed’ error Hi all!

    I am an absolute beginner so please forgive the very simple level of my knowledge.

    I followed a simple tutorial on YouTube showing how to create and build some basic AR for a phone App.
    I successfully built a test Android App which uses a Vuforia trigger to show a simple 3D object which I had textured with some basic PNG images. It worked great - first time!

    Then I created more parts to my model and textured them, built the App again but this one will not install. I just keep...

  • ARKit Detection Progress I've seen some applications in iOS that have a tracking progress bar, basically telling you how much you left you have to move your phone around before you can place object in the scene. Is it possible to do that in ARKit?
  • Lightweight Render Pipeline + Post Processing w/SteamVR Is anyone able to use the Post Process Profile with the new lightweight render pipeline for their SteamVR project? When playing the scene I'm able to see the effects of the post processing in the Scene window of the editor but it isn't applied to the game view or the view in HMD.

  • Oculus Rift – Render to texture or lower resolution Hey here,

    I'm currently experimenting with some visuals and I would like to give a game a very retro look, and among other things I would like to get very noticiable jaggy borders (I know this probably goes against the standard guidelines but I want to give it a try and see how it looks).

    In none vr mode I would render to a texture (lowering the resolution) or simply decrease the resolution in the player settings, but how would I go about it with an VR-Oculus project?

    I have searched for...
