So I have a setup where I am loading googles 3d tiles in an offscreen canvas and have that cameras rtt being passed to a texture in my main threads scene.
But for some reason when I try to export the scene as a glb from the worker then pass the blob back as an arrayBuffer or any other option for communication between the worker and the main thread the model always comes back blank. Even though the data seems to be there something along the way no matter what I do causes the glb to be valid but not have any geometry data. It will load into blender and see the hierarchy I would expect but no geometry.
Is there something about the offscreen canvas that is not allowing me to actually parse the context or something? I would assume turning it into a glb blob and passing that back to the main thread where I duplicated the download process for the GLTFData.downloadFiles method on that blob would work. I know you cant pass complex objects but what would make the blob not work?
I can put together a PG but before I did, wanted to check that this is expected behavior from a worker thread scene.
