  • WorldAnchor problems Hi Unity Forum Readers,

    I'm coding an app that will be shown to a Client this coming Wednesday, so help now would be a lifesaver.

    I Need one reliable WorldAnchor. I have an object that has a script attached which implements tap-to-place, but I've Extended the behavior so that when the user places the object, a WorldAnchor is attached and saved using a WorldAnchorStore.Save() call (this happens after deleting any previously saved anchors with the same id, of Course).

    I saved an anchor in...

  • Disable, Enable and Reset ArCore Hello,
    I'm working on a geo-referenced app, to discover some AR placeholders in several locations.
    To preserve the battery I think to disable ARCore while the player is just walking to the new location (but the app must stay open because there's a map in it that show the placeholders positions).

    1) So to disable ARcore I use -- arcoreSession.enabled = false;

    2) Next. to enable it again I use -- arcoreSession.enabled = true;

    3) At the same time I have to reset AR camera position (to...

  • In apple’s app review, arkit is not working Have you ever see this happen?
    We test nearly all device and this never happened.
    But in apple's review, our app got this pic, arkit is not working, all background is black.
    (I am sure camera is not covered and app has the camera authority)

  • Load 3D FBX model in runtime from sharepoint Hey Guys, I am trying to load 3D FBX models in runtime to a AR scene. I am using vuforia and AR Kit SDKs. Please help me find a solution. The idea is to load all the models in a secure sharepoint and access the models in the AR camera scene. Thanks i...
  • How do I cast shadows in ARCore? Hello there,

    I can't find a way to cast shadows in ARCore, is there some solution to this? I tried with planes and shadow shader that I use in Vuforia, but it does not work with ARCore.
  • Looking for the best tool for my needs (AR with streamed video). Hi guys,

    I know there is a large variety of tools that implement AR with Unity and I am looking for advice on which of those tools will best meet my needs.

    Here's what I require:

    1. Being able to use a video stream from a server as my input, rather than the camera of my device.

    2. Strong and accurate SLAM capabilities (Not requiring image recognition of a predefined image).

    3. Ability to integrate the use of GPS and compass data to improve accuracy, as well as being able to receive said...

  • Calculating time till photons Hi,
    I'm trying to calculate the time that is going to pass until the rendered image is displayed by the VR display (aka time till photons) in Unity's OnPreRender() event on an Oculus GO. Sadly the OVRPlugin provides no method to calculate this.

    I think this shouldn't be to hard to do as the display is showing the image in a fixed interval (= the display refresh rate), if we measure how much time passed since the display showed the last image it should be possible to estimate when it will...

  • Best practice for scaling placed objects with new Ground Plane markerless tracking What's the best way to deal with placed model scale in Vuforia? Simply scaling the model down is not really an option due to breaking Unity physics and particles.

    I'm trying to transition a project to Vuforia Markerless Tracking / Ground Plane that used the ARInterface scale methods mentioned here (currently working fine with ARKit) so that things like physics and particles work at real world scale but placed model...

  • ARCore: Can AugmentedImage with tracking status Stopped be re-used? Once augmented image gets status "Stopped", it can't be re-used for tracking, even if it's scanned again. Is there a way to fix this? If so, how? I couldn't find any API for that.
  • Keep ARKit FeaturePoints’ particles In the PointCloudParticleExample, I am trying to get the feature points to last longer than just the current frame.

    It seems like changing the ParticleSystem values isn't doing anything to the result. Is that because the lifetime parameter is not connected into the example script? If so what is the line of code that I would need to add to get the particles to persist fora set amount of time?

    Or is it because the particles are only updated per frame? Are they deleted thereafter or is it...
