I tried all kind of GLTF, and the error I kept getting is "File name too long"... not sure what's going on...

When using monster.gltf animation from Khronos Group:

Hi @enzyme69, thanks for trying out this tool and flagging your issues!

Did you build your USD against version 18.09? Some of the API calls I am using, such as CreateBindTransformsAttr are not available in earlier versions of USD. Updating your USD should at least resolve this error.

The "File name too long" error is because I have not handled base64 strings yet during conversion, so it only handles glTF assets with external texture references. I plan on supporting that very soon.

The last error is a bug, since shutil.copyfile does not overwrite files in the same directory. As a temporary solution, can you try running this command?:

python gltf2usd.py -g monster.gltf -o monster/monster.usda

This should create a new directory called "monster" and export all the textures and USD file within it. I will work on fixing the shutil issue.

Again thanks for trying out this tool and I'll get to these bugs ASAP!

@kcoley You are right with I am needing to update my USD and thanks for Monster example it converts the animation!!! Wooh~ This is exciting :D

Looking forward to future update!

Funny on iOS this USDZ is not animating :D MacOS works.. maybe a bug?

enzyme69 commented 6 years ago

Will file bug report to Apple~

kcoley commented 6 years ago

@enzyme69 great! Btw, I made some tweaks to gltf2usd this morning, so that the animations play on iOS now. Feel free to pull the latest master and see if that works for you.
