Sets the sequence the NPC navigation path uses for speed calculation. Doesn't seem to have any visible effect on NPC movement or actively playing sequence.

To be able to use this, first set NPC:SetIdealActivity to ACT_DO_NOT_DISTURB, set this to any sequence with root motion data and call Entity:SetSequence on your desired sequence. As long as your NPC's NPC:GetMovementSequence has root motion data, your NPC will move to navigation point even though your NPC's Entity:GetSequence doesn't have any motion.
