Omniverse GLB to USD converter errors (with ReadyPlayer.me avatar)

Omniverse Apps USD Composer (Create)
1

Just wanted to confirm the Omniverse GLB to USD converter is still broken in several ways. For example, it fails to correctly import ReadyPlayer.me avatars.

  • The blend shapes are lost
  • Some textures get messed up

Sample GLB file: ready-player-me-with-blendshapes.glb - Google Drive

Note for textures that the hair and arms skin is wrong, but the short top is correct.

(See also previous related thread GLTF/GLB character imports puts skeleton not at root - #14 by alan.james.kent)

Steps to reproduce:

  • Right click on GLB file inside USD Composer and select “Convert to USD”
  • Open USD file

Just wondering if any news - is this likely to be fixed?

@alan.james.kent We’ll track this internally. Thanks for your feedback and patience.

Thanks. I tried the latest release, but materials on my GLB files no longer come through (maybe a change in 105?), so it seems to have actually gone backwards for my GLB files. So I am starting a background project to convert GLB to USD for character models in JavaScript (then I can use three.js to parse the GLB file for me). It’s going to take a while, but it feels a messy enough area that I want to control it better because its so core to what I am doing. If I get something going I will share it as a open source project.
Thanks!
