Pointable Canvas Event works with Quest Link, but not when built to headset.
Hello fellow devs, I am using the RayCanvasFlat that comes with the samples for Meta Interaction SDK for my project. There is a wall object in an architecture scene and I want to be able to use the ray pinch functionality to select this wall and call an event to pop up a menu to interact with this wall. I used the RayCanvasFlat prefab and removed all text and buttons from it, duplicated it 3 times and placed them on 3 sides of the exposed wall: I added a pointable canvas unity event wrapper and in the select part I added my menu scaler. Here is the pointable canvas module settings: When I run the scene in unity editor, and I point and pinch at the canvases around the wall, I get the event called successfully and the menu pops up. However, when I make the build and run the build on Quest 3 untethered, pointing at the canvases still works (I see the cursor and the click effect) but the unity event to scale up the menu does not work... Any ideas how I can debug this or fix it? If there is also a way for me to use this ray interactor + pinch without a canvas where I can see the cursor similar to how it appears on canvas, I would be grateful for directions too. Thanks in advance!
How to modify Grabable scripts?
I renamed HandGrabInteractable to HandleLeft and confirmed that the grab functionality is working well. Additionally, I want to save the position when HandleLeft is grabbed and moved, and create a new object at that position. So, I wanted to add a public bool DropDown variable inside the Grabbable script and set DropDown = true during EndTransform(), but it keeps getting deleted automatically. I'm not sure how to solve this issue. Please help. + Additionally, the PointableElement, IGrabbable properties are not enabled. (The font color does not change.)

When using Meta's shader for the hands + changing the style of passthrough, the hands transparency is not rendered correctly. It happens in both Quest 2 and 3. I'm sure this was working just a few days ago. Could it be caused by the new v64 OS update? Has anyone else seen this recently? This: Instead of
Meta Avatars are nearly useless, and there is no support or documentation.
My company has been trying to implement the Meta Avatars into a game we are developing. As many VR games do, this involves holding many different items in VR with different hand poses. The only example of a custom hand pose, is primitive at best, with the custom pose being 24 transforms with a Skeleton Renderer script. There is no way to model poses accurately, and you can't even see what it looks like with a skin, until you run it. Move a transform the wrong way, and your fingers are a tangled up mess. Meta has spent literally billions of dollars on various software and game development for the Quest, including the Avatar SDK. It absolutely baffles me that there is no available support for it. No good examples, the documentation is extremely lacking. At least give me a hand model or something that can be used to model a hand, other than a pile of bones (vectors). The oculus integration hands look similar, but models are not compatible. Please, someone tell me I am wrong, and I have just been looking in all the wrong places. Tell me there is some actual documentation besides https://developer.oculus.com/documentation/unity/meta-avatars-custom-hand-poses/ Those documents sound like you can just add some joint types to any old hand model and they will work fine.. please show me one that will, because none have worked for us. Every time I search for solutions, all I can find is other people having the same issues. I am about to give up on even using Meta Avatars, because if we can't make the game feel good with them, I'd rather use another avatar solution, or even no avatar at all.
