Huh, odd. The original issue with the load was that it tried to fetch from an invalid path,
which happens because the .babylon loader uses the serialized texture’s name for the source URL (legacy behavior, I think.) It’s surprising that
Texture.ForceSerializeBuffers didn’t work around that. Could you share the new file? Also, any chance you renamed some textures before exporting the scene to .babylon?
Sorry, I know this isn’t the issue you came for!
