Complex Attribute

Calvin has issue ocncerns about performance on Complex attribute.

Jeremiah and his studio didn't see any scalability issue.

Calvin and Matt Johnson are speaking about the compound attributes.

Calvin wants to describe everything at Unreal level in USD. In a static Mesh componant, there are more than 1 thousand attributes. Eith millions of actors with all their compenents, they are wondering how the compound will handle this.
Calvin's team is using Omniverse.

For Jeremiah, if there are perfomance issues, one idea would be to flatten the structure (eg : nested attribute).

Another idea : do you need all the data outside of Unreal?

When Calvin is generating mesh in Houdini, a lot of settings are generated (uvs, etc) So Houdini is adding everything in USD.

Is the compound API ready for this?

How much of this data is needed by the composition arc? 

There should be a discussion on a thread in Slack or Discord. In this forum : https://forum.aousd.org

May we can tag attributes we need to export in Unreal?

Regarding scalability, does using default value help ? It seems that compound API is not supporting it?

The biggest issue is the construction of the structure.

LOD USD Schema - Discussion on what's currently liked / disliked for implementation.

https://github.com/ubisoft/usd-lod-schema-proposal

 the level of control is good.
The original proposal is a draft. We maybe need to better write it down. We need to fork it and heavily create a real one. The Ubisoft one is hypothetical. For example, how do we do HLOD?

Maybe, having more applied schemas would be better.

https://lodbook.com could help on defining what are LODs.

We need to focus on what information is important for LOD to be engine agnostic.

We need to check the Paolo's work.
