I am creating a very simple animation in blender of opening the box flaps and following the link here.
I started to save the blender file under the asset folder in unity. So, I could see the effect of the changes in unity.
Everything was fine, and the box in blender and unity looked the same. However, as soon as I reach the step where we are animating the box and setting default position for frame 1 and close the top lid at minute 15:30 in the video and then I actually save the box to see how it looks and the box becomes sort of disformed.
If i open the flap again to default then it looks correct again, any sort of rotation of the flap disfigures it in unity. The rotation is around x axis. Any pointers or help of what i am doing incorrect in this case. I tried using a blender add on to fix rotation , however it became worse.
