Hi everyone

I am used to working in Unity but have started a project in Unreal (4.26.2) and have found the CC3 to Unreal workflow MUCH better than the Unity one (probably due to newer/better autosetup plugin) but I have noticed that when I retarget animations to CC3 characters, the shoulders look... well... not quite right. They seem to be pulled in too close and "maybe" a touch too high.
It is mostly noticable with Idle animations and mid stride on walking and I am not saying it is all distorted, just they don't quite look right.
As a test I retargeted a Metahuman to the same animations and they look great so it has to be something odd with the retargeting to CC3 characters.

I have kept everything standard and not played with any of the humaniod settings in the retargeting area, but is there maybe a known problem in this area that needs adjustment from the stock settings,

Thanks for any advice.

Can you show a picture of your problem?
In the Skeleton Tap , you can change to "animation scaled" ...looking for a tutorial....also when exporting from CC3 or IClone use the UE4 A_pose.

Hey Bassline303

Thanks for such a speedy response. I will pop through a screenshot as soon as I get back in front of my UE4 PC. 
I had already been applying the UE4_A-Pose and ensuring it is the first frame in the export settings and also ensuring the TA0 setting is set on import.
I hadn't tried animation scaled in the skeleton though, will give that a shot and report back again.

Once again, thanks for such an amazingly fast response :)

Hey Bassline303
Here are two sample screenshots, I tried recursively setting everything to animation scaled as well and it didn't actually change anything at all.
See how the shoulders look a bit too high and the under arms seem to be pulled in too close to the body (I think from the shoulders).
Am I just being too fussy? I just know the Metahumans don't have this odd look so it is bugging me LOL.

haha , the Meta Humans have a lot of "pose morph corrections" as a BP.
What you also can do is to offset the shoulders in CC3 before exporting , it always depends on which animation you want to retarget :

Magic! thanks Bassline303, I am thinking the pose correcting of the shoulders down might help here.
I actually didn't know that existed. I was starting to think I was going to have to change the retarget pose in UE4.

I will give this a go and see if it works for me.
I didn't know that about the Metahumans, I really like them but they are sooo heavy, even with turning off strands. Could be those pose corrections running in the BP.
Definitely would prefer CC3 if I can just get these shoulders looking a bit more natural.

Thanks again :)

Jason, what does the character look like in CC3 and in Unity, do you see different shoulders vs Unreal?
