Hi. On page 79 there is a diagram of a vertexBuffer that shows the stride between position attributes as 36 bytes, but the stride, as returned by the vertex descriptor, is actually 12 bytes.

Well done! That’s made it through a couple of editions.
A vertex descriptor format .float3 is made up of three floats, each with a stride of 4.
However, the simd_float3 is padded for alignment, so will have a stride of 16 bytes.
