And no matter how cool we believe it is to use Gantry on macOS, there is an extra magic when playing with it on iOS youtube.com/shorts/Qw0Le... #OpenUSD #RealityKit #iOS

Gantry can convert .gltf, .fbx, .obj, .ply formats to .usd(z). It does this natively and on the device, so you are already working on .usd by the time you see the model in the viewport. youtube.com/shorts/nx1ge... #OpenUSD #RealityKit #macOS

Gantry needed to be battle tested before it could be considered a useful converter, so we tried it out with tons of 3D models around. Here's a list of the most useful ones so far: https://gantry.reality2713.com/models/

Today is the release day of a tool that we wished we had sooner. Gantry converts 3D formats to USDZ using OpenUSD native tools, exports images, optimizes textures, and makes the whole process look easy. will get a 50% discount during the launch.

OpenUSD has a closed, enumerable set of SdfValueTypeNames. Swift's type system is open-ended and Turing-complete. RCP cannot support all Swift types—it supports the USD-serializable subset: Swift types that map directly to SdfValueTypeNames, plus special cases like enums and optionals.

I was working outside today, and the terminal was totally unreadable in the sun. Long story short, here is a light skin for Hermes and a skin configurator... https://hermes-skin.reality2713.com

I am not sure what we are doing with RealityKit. It cannot handle relatively complex models and features; the focus on aesthetics and GUI support is excellent, but we require a robustness and industry-standard iteration

We may or may not be dealing with App Store rejections at the moment to get something cool out the door...

Beautiful selection outlines with RealityKit PostProcessEffect https://elkraneo.com/realitykit-outline-selection/

.glassEffect tints depending on the background. This worked for all components in our viewport except for one; after some debugging, it seems that the total area for a view to opt in for this behavior is 4096. Our current theory is that this is related to TBDR tiles

I am absurdly happy with this selection outline

I have been upgrading Prelight and Deconstructed to SwiftUsd 6, containing OpenUSD 26.03. This brings new opportunities for validation and diagnostics. I've also continued with the RCP component fixtures and added notes to the Uncannyuse site. More updates coming soon...

usdchecker --arkit is deprecated, and usdchecker now uses only the validation framework. usdzip’s ARKit option is also deprecated and explicitly called out as legacy behavior. https://github.com/PixarAnimationStudios/ OpenUSD/blob/1818e14bae0036ac4bc7b4e60826b5797076a4fe/CHANGELOG.md

I've been researching the overlooked work that Reality Composer Pro does with open-source technologies like OpenUSD, and I'm glad this resonates. Thanks @salestech.bsky.social & @pixelpartner.mastodon.gamedev.place.ap.brid.gy visales.de/openusd-ohne...

uncannyuse now has schema pages for Reality Composer Pro components—showing the exact USDA block RCP writes, field-by-field with types and sparse-authoring behavior, plus annotated fixture examples. 20 components covered so far. https://uncannyuse.com/features/accessibility-component/schema

Imagine using Reality Composer Pro in light mode 😎

We need a "caniuse" for RealityKit & RCP. That's what @kahunamoore.bsky.social commented after yesterday's post, and it is such a great idea that it had to be done uncannyuse.com

RCP exposes less than half of RealityKit's component surface. 28 of 61 types. 5 visionOS-exclusive. There are 6 brand-new components in version 26.0, but none are available in the RCP version yet. Next on the Deconstructed series. https://observablehq.com/d/4e1ffd6d2df015f9

RCP transforms are persisted in the USD file as a series of xformOp. RCP also creates and stores a custom rotationEulerHint, which includes a precalculated Euler (radians) derived from the orientation quaternion. https://elkraneo.com/deconstructing-reality-composer-pro-inspector-basics/

The .realitycomposerpro "document" is a bundle inside an SPM package. Not the folder you see in Finder—the actual document is Package.realitycomposerpro/, which contains metadata, with Sources/ next to it for Xcode integration. https://elkraneo.com/deconstructing-reality-composer-pro-document-type/

Reality Composer Pro silently rescales every primitive to 20cm bounding. USD defaults are 2m. Deliberate choice—AR table-scale. Undocumented, but obvious in hindsight. https://elkraneo.com/deconstructing-reality-composer-pro-scene-navigator/
