Hello, I’m trying to find out how the values found in
are related to the values in the <float_array id=“Box01-mesh-positions-array”> (see code pasted below of a simple cube)
I know that the values in
are accessed 3 at a time in this example, and that the ones on offset=“0” are related to the <float_array id=“Box01-mesh-positions-array”> somehow (or are they?)
But when I begin to read the
I see
0 9 2
and I can’t figure out what these numbers mean, when there’s a 9… it seems like it couldn’t be referring to the vertices because there are only 8 vertices, this is just a simple cube.

edit: after about an hour of testing, I finally realized it’s parsed as one value for every 2 values read in:
0 2 3 3 1 0 …
Just in case anyone else had trouble.
