Do never select Embed Textures, I think this is what's causing trouble. Also do not forget to drag the whole exported folder into Unity, not just the FBX model.

Sorry, wrong screenshot, I used Unity, default settings with "deleted hidden faces" enabled. 

Hello, I tested your script for exporting multiple animations, and while it works for standard motions, it does not support iMotionPlus, which is my case, because I need to animate props and attach them to character, which is not supported by standard motions. Moreover, the import process is quite tedious with so many animation files - I have to set avatar and all other settings one by one in Unity, as Auto Setup 1.01 does not create it automatically due to missing Hips bone. I will therefore stick to my proven and the only fully functioning worfklow for now - 1) export character in CC3/iClone 7 and 2) export all animations in one go using 3DXChange.

Hi, thank you very much! I will test the script later today and let you know how it works out.

I will strongly suggest you to use iClone or CC to export Unity fbx, because the fbx from 3dx7 isn't compatible with autosetup because we add lots of info which don't implement in 3dx.
According to your request for iClone, I made a simple script that can allow you to export multiple motions with selected avatar without mesh, you can try it.

Hi sabrx,

Thanks for addressing this out. We are now checking this issue.

None of that, I am using 3DXchange 7 for exporting multiple animations with one character, because iClone does not support this. However, it is roughly the same config as Unity in iClone. Anyway, what does this have to do with it? With the previous version, it worked well regardless of configuration.

I want to confirm that did you use Maya or Unity preset for exporting fbx?, thanks

Hello, I tested this latest Unity Auto Setup, specifically AutoSetup 1.02 for Unity 2019.3 in 3D version and it does not work well. While the "Hip" bone error has been fixed by migrating to this new version, and avatar is being setup correctly now, this version causes much worse errors: animations stored with the character are now not editable in Unity because of the plugin, even when it is turned off in Tools menu. Any changes I make to the animations (e.g. set Loop Time, Clamp Ranges etc.) are always reverted back despite confirming them. It must be the plugin that's doing this, because I reverted back to version 1.01 and it started to work again. Could you please fix that and publish a new version?
