Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Has anyone tried creating a New Volume with the Medical Example scene?


I am working with the Medical Example scene in HoloToolkit-Examples. The scene works fine. Now I am trying to create a New Volume. I am using the BrainSlices directory and image files for testing and left the values exactly the same.

However, when running Create->Volume Information, it reports the following error:

IndexOutOfRangeException: Array index is out of range.
HoloToolkit.Unity.VolumeBuffer`1[UnityEngine.Color32].SetVoxel (Int3 pos, Color32 val) (at Assets/HoloToolkit-Examples/Medical/Scripts/VolumeBuffer.cs:54)
HoloToolkit.Unity.VolumeImportImages.ConvertFolderToVolume (System.String folder, Boolean inferAlpha, HoloToolkit.Unity.Int3& size) (at Assets/HoloToolkit-Examples/Medical/Scripts/VolumeImportImages.cs:52)
HoloToolkit.Unity.VolumeInformationEditor.OnInspectorGUI () (at Assets/HoloToolkit-Examples/Medical/Editor/VolumeInformationEditor.cs:40)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)




  • any update tried as above an received same error

  • I actually came across the same issue a year after you. Have you solved the problem? I got the same error message and am not able to create a new volume. Even when I'm using the same images as the sample, it always says "Array index is out of range". Or does anyone know how this issue can be solved?
