USDZ Texture reading support (FTV-202)(USDU-230) about usd-unity-sdk

[jcowles]

It is currently supported, however reading textures from USDZ is not; this is the reason we haven't included it in the file open dialog filter. Until then, you can manually select the file and it will load, however it will not include the zipped textures.

Once textures are supported, we will enable USDZ in the open dialog.

Hello,
Is there any additional work being on importing USDZ directly? This would be very awesome feature to be included. Thanks!

Hi bambamyi, we are not working on any USDZ features at the moment. But we are in process of planning work for next year so we'll see if we have room for USDZ improvement.

[bambamyi]

That is unfortunate to hear. I hope you guys decide to add direct USDZ support quickly. Yes I can uncompress the usdz file and reference the textures and stuff but it really seems misaligned that you guys are on top of ARKit support but not the file format used by ARKit...

I am having trouble attaching textures to a USD file that I imported into Unity. It was previously a USDZ file that I unzipped, but I can't figure out how to reference the textures. Any place you could point me to that would help me to do that?

If you have unzipped the usdz file into a folder, setting the Material property on your Usd Asset to Import Preview Surface should get you the textures. If not can you send the usdz file for us to investigate?

That worked. Thank you so much! I appreciate it! Griffin

Hi Julien, So, using Import Preview Surface worked correctly, but now it seems that I have lost my skeleton structure (the hierarchy of joints). Whereas before, all of the joint nodes were included, now there is only a Skeleton node. Thanks for your patience, Griffin Holt

Hi Julien, I thought I’d give you some additional details about what I’m seeing. I have attached a link to the usdz model I am trying to import properly into Unity: (it is the same usdz model that Apple used for its ARKit 3 demonstration) https://developer.apple.com/videos/play/wwdc19/607/ <https://developer.apple.com/videos/play/wwdc19/607/> The problem I am seeing is this: Sometimes, after unzipping the usdz and importing it into Unity, I am getting the whole skeleton structure but am not able to any of the materials (the model just appears black). Other times, after unzipping and importing, I am getting the mesh and the materials attached, but the entire joint hierarchy is gone. My goal is to get both the mesh & materials attached and get the whole joint hierarchy. Could you help me understand what I am doing wrong? Thank you, Griffin Holt

Any word on the problem I submitted above?

[lee-aandrew]

Hello @griffinbholt

I am doing a issue clean up task using our latest dev branch, and with this issue, I cannot reproduce your case with the skeleton structures missing - I've used assets from Apple, specifically "gramophone", "robot_walk_idle", and "toy_drummer" and for all 3 assets, importing directly from USDZ and unzipped USDC, I could not reproduce the skeleton structures being missing, and so I believe this has been fixed by our more recent bug fixes

But just in case, if you are still following this issue, please pull our latest dev branch of the package and try again, and if still problematic it would be very much appreciated if you could send us the exact asset you are having the skeleton structure problem

The texture missing portion, we are aware and is tracked in our internal bug tracking system

Thank you!
