One of the reasons I went with GLTF files is that blender will export models “linked” in. This is fantastic, because I can build a library of props and parts, and when I update one prop, it’ll update in all of the other files where it is linked. All I need to do is re-export to GLTF.
However, I’ve found that I get an error if I link the same blender file more than once:
Uncaught (in promise) Error: /nodes/8: Invalid recursive node hierarchy at GLTFLoader.loadNodeAsync (glTF.js:3725) at ExtrasAsMetadata.loadNodeAsync (glTF.js:7288) at glTF.js:5149 at GLTFLoader._applyExtensions (glTF.js:5126) at GLTFLoader._extensionsLoadNodeAsync (glTF.js:5149) at GLTFLoader.loadNodeAsync (glTF.js:3720) at loadNode (glTF.js:3742) at GLTFLoader._loadMeshAsync (glTF.js:3809) at GLTFLoader.loadNodeAsync (glTF.js:3758) at ExtrasAsMetadata.loadNodeAsync (glTF.js:7288)
I can get around this by “appending” the blend files instead of linking them, but then I have to delete and re-append every time I update one of these props. Not ideal.
Does anyone have any pointers to get around this error? Can I plug into the GLTF loader and make a copy everywhere there’s a link?
