I'm looking for a position as either developer or consultant to work on #digitaltwins #openUSD #usdkit #realitykit.
I'm based in Germany

The sample project for the new SpatialPreview framework is pretty good. It has example of document (image) and UDS preview sessions. As a nice bonus, they also use the new USDKit to create a custom USD stage, modify the layout, and play an animation.

USDKit beta 2 → beta 3 jump is variants
- USDPrim.variantSets
- USDPrim.VariantSet
- VariantSetCollection.add
- VariantSet.add
- setSelection, clearSelection, blockSelection
- selection, authoredSelection, variantNames
- withEditTarget(layer:_:)

Also new: USDPrim.transform(at:)

For those lucky enough to be on macOS27, here's a TestFlight of Gantry powered by USDkit, we call it Gantry27 (and sure, we put more thought into the app than the name)
testflight.apple.com/join/1MXM41Wm

while we wait for the review of the first Gantry27 beta, we kept going and started with the implementation of Spatial Preview so we can start really enjoying the benefits of USDKit

UPDATE: After a closer look, the beta-2 SDK (27A5209h) does expose this USDKit typed layer in the public .swiftinterface — but underscore-prefixed (_get/_set/_readArray/_writeArray/_getElement), i.e., SPI: linkable today, but not yet finished API and subject to change between seeds.

USDKit Beta 1 had no typed way to read or write vector values. Beta 2 adds USDArray<T> for scalars, Float16, GfVec/GfHalf/GfQuat, and GfVec3f with get/set/readArray/writeArray/getElement over attributes, UsdAttributeQuery, layer fields and specs.

Not in the public interface yet.

Gantry v27 beta — powered by USDKit

PathExpression pattern matching; generic applyAPISchema (this is how the WWDC accessibility demo works—schema name + raw attribute strings, no typed API).

What Apple's USDKit brings:
USDStage, USDPrim, USDLayer, USDValue/USDToken, USDTransformOperation. Stage open/create/save/reload, export, exportFlattened, exportPackage (AVIF textures + mesh compression options); full prim/attribute/metadata/custom Data read-write

- USDKit: lots of changes that I can't understand
