[DRACOLoader] Decoding failed: Unknown minor version

Questions

Hello All,

I have compiled draco_encoder from the latest official git repo, I am using this encoder to convert some OBJ files to drc. I am using THREE.DRACOLoader to load this drc files, but i am getting Unknown minor version error.

I tried looking for way to find version number supported, but didnt had any luck.

Anyone has any idea how to check the version number support for decoder and encoder.

** Note I am not using gltf loader, since i have certain custom needs like supporting custom materials and shaders.

Thanks,
Dinesh

@Mugen87 I went through that issue before posting here.

@looeee here is the file i am trying to load.
bottom_standard_backleft.drc (86.4 KB)

I am trying to look for a way to find version numbers, so i can encode files correctly

I don’t know if you can see the version number in the source files. But you definitely know the version of your encoder. DracoLoader uses a bunch of JS and WASM files for client-side decoding. Does it work if you replace these files in the three.js repository with files matching your encoder version? The following link leads to the latest ones.
