I’ve made a simple animation in Blender using key. After importing the model to Unity it looks good, but while playing the animation I did the model starts gradually looking like it’d look if you turned on shade smooth in blender, and then gradually go back to normal. I’m not sure where the problem could be, and I can’t find the problem online.
My guess is that being different meshes messes with Unity maybe? I don’t know if that’s anywhere near the true reason though.
EDIT: Tried to make the two parts not occupy the same space (still same model) and the same effect stayed, so that’s def not it. Added an image too
additional info:
The animation was done using keyframes on shape keys.
the moving part and the rest of the model are two separate meshes, but one model
No duplicate vertices are present
This takes place both in the animation preview and in the scene view
.FBX export settings:
Object Types: Mesh
Forward: Z Forward
Up: Y up
Apply Unit
Use Space Transform
NLA Strips checked off
Force Start/End Keying was tried both on and off
everything else I left on default
Mehs in Blender:
Mehs in Unity, at the start of the animation, in the animation preview:
Same mesh, in the middle of the animation, in the animation preview:
