Hi Miranda. I missed your kind reply. These days I'm using Act
orCore animations with CC4 models. I use Soupday's CC importer.
I change the ActorCore FBX animation avatar from Generic to Humanoid. I've tried both 'Create avatar' and 'use other avatar (robot)' but still see an error with the hip bone animation.
Can this error be disregarded?
Attached are the settings for this model. The CC4 model posture with animation applied is slightly bent over at the hips.1. Avatar settings. Model bones in Scene view look good.

2. The Act
orCore animation import error. The CC4 character's posture appears bent over.

3. Act
orCore Looking-stand-m animation import settings.

4. Act
orCore anim rig settings (Unity)

5. Act
orCore Look-stand fbx import model settings.
