Normal index 12868 is out of bounds

congtong commented 4 years ago

When I execute this command node obj2gltf/bin/obj2gltf.js -i model.obj -o box.gltf

An error like this occurs： Normal index 12868 is out of bounds

@congtong can you upload the obj model so we can help debug?

@congtong there's a few nan's in the obj which is causing the parser to skip those lines

Are you using Vectorworks? I saw a similar bug report in assimp: https://github.com/assimp/assimp/issues/2428

It looks like assimp decided to coerce NaNs to 0s: https://github.com/assimp/assimp/pull/2429
