Future: Universal Scene Description export

Any update on when USD import will be worked on? I need to bring 3D scans in via GLB or USDZ but most often USDZ works better in other CAD programs. Currently going via Blender as FBX or OBJ works poorly but I plan to try Rhino 8 GLB import soon.

Hi,
We will start to work on it this month.

According to this AEC magazine article, USD format has the potential to become the one and only ‘allmighty’ file format.

It would be interesting to learn what parts of a Rhino scene it can describe. All of it? Curves, surfaces, the lot?

Maybe one day it even could be a cloud solution for teamwork?
Interesting stuff…

We are only writing the data that we know other applications can currently read. For now that means meshes and curves. When other applications are found that support more data types we will see what can be done to get that data into the other applications.

Materials, textures, light sources, pointclouds etc, too?

Materials, textures and lights are already exported. If you have a case where you need a point cloud and have a program that supports reading point clouds from USD, let us know

Hi will the USD exporter also be available for Rhino7 Users?

No; the USD file exporter was added to Rhino 8 and will not be added to Rhino 7

I tried this feature but unfortunately without luck. Both Substance Painter and Sketchfab is showing that the mapping is screwed.

Can you please allow uploading usdz files on the discourse?

I’m not sure what that is but I have logged it here and will look into it.
Thanks for reporting.

I don’t think there will be one and only almighty file format, same as there won’t be one and only almighty programming language or one and only geometry modelling tool :slight_smile:

Each tool has it’s own strengths and weaknesses. I think both GLTF and USD try to achieve something similiar, which is describing a 3d scene as universally as it could be. This goal is compeletely different than e.g. IFC which is mostly focused on storing AEC data in a standardized way.

Issue I have personally about such universal solutions is the fact, that if you can describe there hundreds different geometry types or other features then you don’t really know which software will export and import which parts of it. So e.g. software A will export textures, but software B won’t import it. Software A will export curves, but software B will take only meshes. Also your question there about what parts of a Rhino scene can it describe proves my point :slight_smile: But I know that for many people this is how it is, a normal thing, or they don’t see a problem :slight_smile:

Any chance we can export to USDZ like blender does? See this

I believe we already support writing to usdz

@Devang_Chauhan - check out the Rhino 8 Evaluation, as it supports writing usdz files.
