CFG variable to make a part reflect over an axis when using symmetry mode in SPH?

[1096bimu]

I know it exists in some part I used to have and it works, I just can't find it. It's something like reflectAxis.

I really hate how there is no spell correction and everything has to be spelled so exactly I can't write any CFG without copy and pasting from other parts.

There are mirrorAxis, mirrorRefAxis and mirrorVector properties in Part, although I'm not sure if they actually mirror stuff or just control the rotation in the SPH.

I don't know what text editor you're using, but many do offer keyword highlighting that you could use to ensure your variable names are correct (or use an add-on spellchecker and a custom dictionary).
