![]() ![]() Animate the root boneįor your armature, select the action that requires walk cycle keyframes, or start a new action. ![]() Typically, these will be the feet IK bones and the torso bone, but may in some cases include the eye target bone and other miscellaneous controls. Also determine the ‘Control Bones’ of the character that are effectively parented to the root bone. Your character will likely have a ‘master’, or ‘root’ bone. This can be a little tricky to find in some cases, but it’s often twice the distance between the feet IK bones in the traditional ‘contact’ pose.ĭetermine the root bone and the control bones You will also need to determine the distance that the character must travel in that frame range so that the feet have no slip. The walk cycle will have a start and an end frame for the walk cycle motion, and the keyframes on the first frame should be the same as the keyframes on the last frame. I’ll assume you character already has a ‘static’ walk cycle. When it’s finished, the keyframes of the root bone are removed. The addon will create a new action and will then take keyframes from the static walk cycle and place them at the appropriate intervals for the speed of the root bone, and it will add the offset of the root bone from it’s starting position to the keyframes of control bones like the feet IK targets and the torso. The idea is that you animate the root bone of the character to follow the required path. Once installed, enable the WalkUnpack addon. Use the Install Addon button to select the txa_ant.zip file. Open Blender and go to Preferences then the Add-ons tab. Installationĭownload the ZIP file the link above. This addon aims to treat the static walkcycle as a motion template which can be unpacked and applied to the motion of the root bone of the character. Customising the animation is also difficult as the keyframes are relative to the moving root bone.ĭeveloping the walk cycle as a ‘progressive’ cycle alleviates some of the issues, but there are still downsides. To use it the root bone must be animated to smoothly move at the walking speed, and it’s hard to avoid foot slipping. For animations and films, this is not ideal. ![]() For games development, that’s generally all you need. It’s common to develop a walk cycle so that the character walks on the spot.
