relative ipo's

is there a trick to get relative vertex ipo’s to work in the engine or do they not? i made one and it shows up when i move the frames or when rendering but not while in the game. im new to blender but i know how to make normal ipo’s play through logic bricks. just no luck getting the relative ipo to show up.

nope they don’t work
[neither do absolute vertex keys]

you’d have to use armatures
[which, btw doesn’t change the bounds of the object or the collision faces…]

also, dloc drot and several other object ipo channels dont’ work

thank you for your speedy reply
