I did some tests.

first of all, everything works like a charm on the Quest (default browser), both grabbing object and materializing them from distance with the in-world cursor works perfectly.

On desktop (macOS, Chrome):

I made several test about objects geometry and the issue seems unrelated with it. I scaled objects, reset their transformations by "apply all transform" in Blender, moved their origin, changed the scale applied from the spawner node itself. I now have some mugs which are spawned with a null spawner transformation and sometimes they work, sometimes they don't. I cannot see any pattern, it seems completely random.

It SEEMS that the spawner works better with BIG objects (before scaling them my mugs were 1 mt high), but I am not sure if this is just an effect of the object being bigger and less prone to be translated out of the walls, etc. Maybe it is translated exactly of the same amount but you do not notice it just because is bigger.

On mobile devices (tested on Chrome on an iPhone and Safari on iPad Pro): the spawner works as expected.

I made these tests from a Blender scene, exporting with the Hubs Blender Add-on, with both gravity enabled and disabled, and loading the scene in spoke (via the "add new scene" glb direct upload, NOT importing the GLB in spoke and publishing from there).
