pub fn decode_instance_finishes(bytes: &[u8]) -> Option<Vec<[f32; 2]>>Expand description
Trailing field 2 of every instance record, in instance order (#5984):
[metallic, roughness], NaN where unauthored. A shard whose stride does
not reach the field (v1, v2, or a v3 written by a model without finishes)
reads as all-NaN rather than failing, the same forward/backward rule the
item id follows. None exactly when decode_instanced would refuse the
header or the instance table does not fit the buffer.
