HoloLens 2 and iOS | Depth/Alpha feature for better Hologram quality/stability is available as preview/beta version. |
Quest Pro | Passthrough not available on the QuestPro: the lower FPS resolution available on QuestPro does not allow the application to have a higher precision alpha value, therefore the user would have a poor performance experience in AR mode. |
All devices (HL 2, Quest 2, Quest Pro, iOS) | Encoding method H.265 requires a HEVC package: Users might be required to install extra software components to support HEVC/H265. You can find download links for both the ISAR Full and ISAR Trial on their respective GitHub ReadMe sections - available on the Microsoft Store for a one-time charge of €0.99. |
Unity | If you have upgraded the ISAR SDK in your project (e.g. from 2.6.0.0 to 2023.0.0.0), you may not be able to continue using ISAR because the error message ""There is no ISAR loader active. ISAR cannot be used. Make sure to enable an ISAR Loader trough Edit -> Project Settings -> XR Plug-In Management before using this class" appears, although the check mark in the Project Settings is actually set. In this case please change the string to "HoloLight.Isar.Signaling.SampleServerSignaling" under Edit -> Project Settings -> XR Plug-in Management -> ISAR -> Signaling Implementation Type to establish a successful connection. |
