Hey everyone, as an artist creating content for Vision Pro, I’m looking for a reliable USD workflow, so that I can confidently update geometry and materials in a DCC, knowing how they will render on the Vision Pro. Based on my understanding of USD, this is a fair use case. However, I need help unde…

Yes sorry I meant non-usdz. I see that you’re referencing the file in. Blender has an unfortunate default for root prim in the exporter that breaks material assignments when referencing blender generated usd files in any USD based application. In the blender export options, make sure you provide a…

Hi Campbell, This might be better answered on the Apple dev forums, but I’ll try and help here as well for the workflow parts. I would recommend filing feedback with for Reality Composer Pro at http://feedbackassistant.apple.com Both Blender and Maya can export directly to USDZ so you can cut ou…

Thanks @dhruvgovil , this is super helpful. I will work through some of this, moving to non-usdz files, and report back. I did a quick test with a .usda, but I find that RCP is not importing the materials (though you can see them in the bottom right preview), let alone assigning them. I have attached…

Adding /root did the trick, and I can see in tests how the materials are falling outside of that hierarchy. Thank you! The textures are working for me, but this I guess brings up my next question. Does the rkassets folder essentially become my working directory? With using Blender to work on the as…

I have been playing with this a lot this morning. A few things have helped a lot: Ensuring my USD assets have a proper root Using USDA/C instead of USDZ Working directly in the rkassets folder (for edits) Next steps for me to test out are: how well Blender can edit the materials (I noticed my A…

Since you’re doing all this - I wonder if some it could be worthwhile if you’d be able to do one of these “simple test runs” as you screen record and maybe talk over it as to what you’re doing, why you’re doing it and what types of questions pop up in your head. Those types of “videos” can help for…

To your directory , the rkassets doesn’t have to be your working directory, but all your assets must resolve to within it. So in theory you could work outside of it, as long as you either have paths in your files that resolve there (e.g relative paths) or are putting another layer on top of your co…

Hey @BigRoyNL , I’d be happy to do that. I’ll DM you with some questions and thoughts. @dhruvgovil this is really interesting. I’m still coming to terms with the terminology here, but by “layer” are you speaking about another layer of USD information? Something that handles things like transforms, a…

Each file that makes up a USD stage is called a layer. The stage being the result of all the layers combining together via different types of composition like layer stacks, referencing etc… The nice thing with USD is that you can then separate out your work as makes sense for your individual workfl…

I think I’m getting it now, and I can spot the errors more easily. I certainly didn’t understand the role of the root, and I was able to fix up my Maya examples by adding an form between the stage and the geo, and then making user the materials were also in there [Screenshot 2023-12-10 at 8.21.06 …

Hmm that is odd. It would be good if you can report that regression on the Blender bug tracker.
