Kext Next Particular Reflection Expressions (heehee, that rhymes)

*****************
Apply to position
*****************
posi = thisComp.layer("Movement")
floor = thisComp.layer("Floor")

nPosition = posi.toWorld(posi.anchorPoint);
fPosition = floor.toWorld(floor.anchorPoint);
heightDifference = nPosition[1]-fPosition[1];

nPosition-(2*[0,heightDifference,0])

********************
Apply to orientation
********************

moveNull = thisComp.layer("Movement");

[-moveNull.transform.orientation[0], transform.orientation[1],-moveNull.transform.orientation[2]]
