> In Yidi's previous comment, he suggest to change to passing index to this function. […]

I think that's because at that time, we were not using a for loop (so Yidi's previous suggestion simplifies the code by removing the `blender_reg` duplicates in 8 lines). Now that with the for loop, my suggestion would avoid duplicate array index lookup. @[e-mail]
