I where a bit shocked that with scripting Z = Y and Y = Z, thats confusing. Z = always up and down also in blender. sounds like something got mixed up in HiFi. i hope the change that back to the normal x.y.z. not sure why its reversed. This also explains why @judas got problems with blender and the default settings. And now i see why my voxels are placed wrong, because Y and Z are reversed. thats going to be a big error for long time. WIth some googling am finding both systems, but still suggest to reverse the Z and Y so its for most users normal. Also looks like the Z axe for up / down is more common.
most users are now used to this setup,
blender is useing it SL, opensim , sketchup , looks 3dmax is useing it to.
And High fidelity is useing.
So why is High Fidelity useing a weird configuration. and i think i complained about this before. and expect when more users are going to use high fidelity that this is not the last time.
