@TOADSTORM hi, I played today with roll correction, you were right, I used up vector to be (0,1,0), but after I got front (original), side (front x up) and then re-computed up, so that it is not always pointing upwards<\/p>\n
it was easier, than I thought, but I needed to look at it with fresh eyes<\/p>\n
