Create a path(curve). Create a null.
Path animate the null to the path, set it to tangent and set the up vector. Duplicate the null making it null1. Turn tangent off, reset the orientation to zero. Create a third null, position constrain it to follow the first null. Second is identical in position so ignore it. Constrain the third nulls orientation to the first null. Constrain the third nulls orientation to the second null. Open the top orientation constraint of the third null and adjust the blend weight. You may need to use a rotation offset(probably 180 in Y) to get the appropriate blend. Use the blend weight to blend from the first null to the second null orientation, keying it to adhere to the tangent null as needed. Constrain the object you want animated to the third null. Is that what you want? -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) Mymic Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.

Setting a key causes unwanted rotations & setting a neutral pose doesn't seem to work. I know this is a face-palm moment.... -Paul [https://mailfoogae.appspot.com/t?sender=pgriswold%40fusiondigitalproductions.com&type=zerocontent&guid=be00b853-9de5-4b01-accd-845f578f950d]ᐧ
