When using the center property on SphereCollider, CapsuleCollider or BoxCollider the z-axis offset is flipped on the generated visionOS colliders. This is likely due to the recent change that no longer flips meshes on the z-axis.
I have reported it as a bug here: IN-58015
This is still an issue in 0.6.2. It makes it very difficult to select some objects, because their RealityKit collider is offset from the geometry. What is the timeline for a fix?
Sorry, this clearly slipped through the cracks. We’ll get a fix out in the next bugfix release.
