Avatar distorted when imported from unity

[natstj]

Hi,

I have an avatar from unity that I want to animate with Mixamo and import into Vizard. I am using this Vizard tutorial as a guide: https://www.youtube.com/watch?v=M7fUgkuejgs. I am having the following problem: when I import my avatar into the vizard inspector as a .fbx (the original file type), the avatar appears distorted. If I convert the file to a .gltf and then import it into the inspector, it is not distorted. However, I need it in the .fbx format in order to animate it with mixamo. Do you have any suggestions? Thank you! (pictures are attached)

Best,
Natalie
