Still no solution for that even iClone8???
Had this issue when exporting an FBX to Unreal - was pretty frustrating. Solved it by having the character look at a sphere, then turned on the Bake Constraint Key option before export. Works like a charm (at least for .FBX to Unreal): Here's the link to find the Bake Constraint Key: https://manual.reallusion.com/iClone_7/ENU/Content/iClone_7/Pro_7.4/28_FBX/Exporting_FBX_from_iClone.htm
I am having the same issue now mid 2021! This is really bad!
I am having this look at camera eye problem also. When I animate a character in iClone 7 and use look at camera, set free, pick target, set free, look at camera, etc. I get a good result until I attempt to do a collect clip and turn the animation into a motion plus. When I do a collect clip, I play through the animation, then save the animation as a motion plus with all the correct boxes ticked. When I import the saved motion plus, and play the animation, the eyes vibrate and look in the wrong directions. This is a huge issue as I need to save the motion plus for use in Unreal Engine. Please Advise
I have this problem also and it's pretty disappointing to see how old this post is. Considering I bought all this pipeline software and export content specifically for animating characters so I could export them to Maya and render 3d vr POV movies it feels like a little more then a bug.
