UE5 Control Rig | Aim/Look_At IK | #P1 | Setup Aim_Node

hello and welcome in this video i will show you how to set up control rig look at ik functionality as you guys can see my character properly looking at the sphere and the posture of my character body behaves realistically and if the angle if the view angle between the character and the object is in certain range then my character properly follows the object if the view angle increases then my character will not follow the object and perform the desired animation without looking at the object so this is all done in control rig here's my third person project first thing you need to do is edit plugins go to control and enable the controller plugin and i'm gonna go to content browser right click and create a new folder call this control rig i'm gonna go to animation and create a new controller here's my controlling i'm gonna go to preview mesh and set the preview image to sk manager go to righ hierarchy and import the hierarchy select the sk mannequin mesh and my control link is now done here is the bone hierarchy so first thing first i'm gonna create a new control go to new right click and create a new control i'm gonna call this look at control go to details and select the arrow solid so here is my control for my look at ik i'm gonna right click and set the initial transform from current so every time i compile my control reset its position that i have defined so for setting up control rig look at ik i'm gonna use the aim node like so so for setting up the m node properly we need to set up the primary or secondary axis so the primary axis will be the forward axis forward vector and the secondary axis will be the up vector for example if i open my mannequin animation and here is my skeleton mesh so if i select my head bone here you guys can see the forward axis is the y axis and the up axis is the upward axis so now in my aim node i'm gonna in my primary axis i'm gonna set the forward for y to one and remaining to zero because the first i'm gonna set the bone to hand and you guys can see the forward axis forward vector is the y y axis and the up factor is the x axis so the in my primary axis i'm gonna set the forward vector which is y axis and in my secondary axis i'm gonna set the up factor which is the x-axis like so so now i'm gonna grab my look at control get the control transform and in my primary i'm gonna i have set up the axis value and now for the target i'm gonna use the current control location for the secondary i have set up the axis which is the x-axis is the upward axis and we are not using any kind of control any kind of location we are just using the direction so set this up to direction and for the target which is the up vector i'm gonna set this to z to up like so so here is my aim node is now properly setup and if i move my control you guys can see my head is now properly looking at the control bone is now looking at the control so for setting this up for my upper body i'm gonna use a simple trick just duplicate this aim node three times connect this like so for my first aim node i'm gonna set this to set the bone to spine one second one will be my neck and the third one will be my head so i'm gonna get the translation value of my control and put this in my each primary axis value so now you guys can see if i move my control the upper body properly looking at the note bar it's not in right way this is weird so first the simple fix is to set the weight value accordingly for example if i set this point 3 we are 2.35 and the neck weight to 0.5 and the head weight to 0.75 so here you guys can see now you guys can change the weight value according to your need if i set this to 0.25 now you guys can see the character upper body will behave properly so this is a simple trick we are just using the simple control control rig location and put this into three bones and set the wheels so set the wires properly so if i change the preview to specific animation i'm gonna set this to idle this is not working i'm gonna re open this specific animation and set this to idle and here you guys can now see if i move my control this is pretty realistic my character properly follows the control like so so i hope you guys like this video so in the next video we will set up the proper target so that the character will properly look at the object and if the if the limit is exceeds then the character will not longer default will not will not follow the object so in the next video we will set up that functionality so thank you guys i hope you guys like this video and do subscribe to youtube channel and also you can support me in patreon and gain access to our project files thank you
