v77 Grab Hand Pose Translation/Rotation
Hi, I'm using v77 of the Interaction SDK in Unreal 5.5.4 for hand tracking, and am having issues with a HandGrabPose not following the grab location/rotation when using rotation and location transformers. I am using an object setup with multiple grabbable pieces. My blueprint hierarchy is essentially: Mesh -- GrabbableComponent1 -- SubMesh ---- GrabbableComponent2 ------ HandGrabPose GrabTransformer1 (for main mesh, with free transformer) GrabTransformer2 (for sub mesh, with translate constraint applied) The actual interactions of the meshes work without issue. I can grab the main mesh, and grab the submesh to move it with its translation applied. My HandGrabPose component has the following properties set: The initial posing is fine and the hand will move to the intended pose position, but as the submesh is moved, the hand pose stays in the same location rather than following the submesh as I would like. Looking at the source for hand poses, I can see that the hand pose override is set via a call in OculusInteractionPrebuilts/Rig/IsdkHandPoseRigModifier to HandMeshComponent->SetHandPoseOverride once the grab state changes to Selected, but as this is only called upon initial grab, the required RootPoseOffset does not get updated upon translation/rotation of the grabbed component. This is not an issue for components with only one grabbable where the entire object will be moved and thus the offset remains constant, but for my case with sub-objects the pose offset obviously does change but the hand remains in its initial location. Has anyone run into a similar issue and could recommend a solution or workaround? I'd be happy to provide more information on my setup if needed. Thanks!META XR on Mac OS - Meta Fork & UE standard install both failing
Has anyone had a problem with using the META XR plugin on the Mac? I have tried using the instructions exactly for developing for the Quest using UE on Mac absolutely by the book both using the Meta Fork of UE and doing a standard install and then installing the Meta XR plugin. Both are failing at deploy on my Quest 3. They either stop at the splash screen or crash out at the splash screen. However, with the standard install NOT using Meta XR plugin, it's starting correctly. Reenabling the META XR plugin then results in a crash, typically a shader crash. I'm relatively new to this so any recommendations are greatly appreciated. In case this is helpful: Model Name: Mac Studio Model Identifier: Mac13,1 Model Number: MJMV3LL/A Chip: Apple M1 Max Total Number of Cores: 10 (8 performance and 2 efficiency) Memory: 32 GB Thanks!
Discovered anchors are placed at (0,0,0)
Hi there, I'm trying to use MetaXR anchors for my current project. I previously used Unreal 5.1 with PCVR and I could create, save and reload anchors. I am now trying to do the same in an Unreal 5.4 standalone project. My problem is that when I save the anchor, and I reload it with its UUID, it spawns at (0,0,0). Using the logcat from Android Studio, I found out that there were two errors, one pretty seamingless : SP:AF:AnchorFramework: getAnchorUuid can't find anchor for handle 4 And the second one, which I think is the real problem : [XRCMD][failure] [XR_ERROR_SPACE_COMPONENT_NOT_ENABLED_FB]: xrLocateSpace(*(XrSpace*)space, baseSpace, ToXrTime(GetTimeInSeconds()), &spaceLocation), arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.cpp:13440 (arvr\\projects\\integrations\\OVRPlugin\\Src\Util/CompositorOpenXR.h:317 My blueprint is ugly right now, but here is how I discover and save anchors :
