	==Custom animations - blueprint fix==		==Custom animations - blueprint fix==
	If you want to replace or complement ALS's locomotion animations with your own, and do not want to follow the convention of animated IK bones (ALS expects locomotion animations to have motion tracks for the IK bones that exactly replicate the motion of the actual foot_l and foot_r), you need to modify the animation blueprint (either Mannequin_PostProcess_AnimBP for ALS2, or Mannequin_IK_AnimBP for ALS3), as described [https://forums.unrealengine.com/~~unreal-engine~~/~~marketplace/107921-~~advanced-locomotion-system-v3/~~page30~~#post1488046 HERE] (ALS thread on UE4 forum, post #442). In the Anim Graph, disconnect the "Use cached pose 'Sub-Graph Input'" and "Local To Component" nodes and add two "Copy Bone" nodes between them and the first "Transform (Modify) Bone" node of the "Foot IK" block. For both these new nodes, check "Copy Translation" and "Copy Rotation" and set "Control Space" to "World Space" (in the "Details" panel on the right). Set the source and target bones like on the picture in post #442 (copy from foot_l to ik_foot_l and from foot_r to ik_foot_r).

	After you to this, you can configure the animation blueprint to use any locomotion animations, including those that do not contain animation tracks for the IK bones at all. Also, the "Translation Retargeting" value "Animation" (for the Skeleton Asset) becomes completely irrelevant, since the animated position of the IK feet (if available in an animation) will be overridden by that of actual feet immediately before foot IK processing.

	For simplicity we are discussing characters that have already been carefully adapted for UE4 in Blender or such: the skeleton is assumed to have the same layout as that of Unreal's SK_Mannequin (same bone hierarchy, including the auxiliary IK bones; "twist" bones are optional); the bones are assumed to have the same names as in Unreal's Humanoid rig; the local axes of each bone are supposed to be consistent with UE4's conventions (primary bone axis is either X or -Z, secondary is typically Z or -Z). A good example of such a character can be obtained if you export Unreal's SK_Mannequin to FBX.

	It is very frustrating when you import a Mannequin, make sure its skeletal mesh has exactly the same settings as the included Mannequin (including the Physics Asset), but somehow the foot IK does not seem to work. In ALS3, the new character is actually expected to have correct IK immediately upon import - indeed, the default "Post Process Anim Blueprint" (under the Skeleton Mesh section in Asset Details for the Mesh) is None, which is consistent with the corresponding setting of the included Mannequin mesh. In ALS2, the included SK_Mannequin has, in the same field, the setting "Mannequin_PostProcess_AnimBP", so it is necessary to open the new Skeletal Mesh in the editor, go to Asset Details on the left, scroll to the Skeletal Mesh section, and set "Post Process Anim Blueprint" to "Mannequin_PostProcess_AnimBP". The confusing part is that even after you do this (set the correct "Post Process Anim Blueprint"), and save all the assets in the project (just in case), the new character will still not appear to have working foot IK.
