Hey All - I’ve followed the official video tutorial to export my CC5 character to ALS in Unreal Engine 5 (I’m using 5.6). However, no matter what CC5 character I export, the aiming animation twists the Arm so gets messed up when aiming pistol or rifle. I’ve tried my own CC5 characters, default CC5 character etc. No luck, they all have this issue. I tried rotating the upper arm bones in the retargeter which helps but then messes the rest of the arm up. How do I fix this? Thanks!
Hi HappyKat100,
It may not be ideal to observe the arm movement using the mannequin character.
Please lower the Rotation Alpha value (see Image1) under FK Chains > (Selected Arm). This function is used to reduce shoulder pinch (see Image2). However, the main problem is that the angle of the clavicle is too sharp, please try to smooth out.
Thanks!
Thanks very much for the response. Here is a before and after by changing the rotation alpha of the clavicles (to 0.1) and arms (to 0.3). Definitely better, although I’m still getting the sharp corner in the shoulders. When you say to smooth out the angle of the clavicle, can you explain what you mean by that?
Also, while this is a bit better when aiming, the arms then go into the body when holding the pistol but not aiming. How do you typically solve for that? Do you have a different retargeter for aiming only??
Huge thanks!

Hi HappyKat100,
Glad to know we have resolved your issue.
Mainly, your source ALS animation is too stiff; you may want to tweak the clavicle bone itself to smooth it.
