Nsight 2021.1.0. ignores offsets when multiple BLASes reference the same AABB geometry buffer with different offsets.
The screen shot shows that the geometry is in the buffer AabbSBO @0.
The offset should not be zero.
In the visualization panel there should be different eight BLASes.
Instead, the 1st BLAS is repeated 8 times (with proper transform).
Rendering and ray query work fine otherwise.
Seems related to Confusing Acceleration Structure Buffer Offsets for VK_KHR_ray_tracing.
