Blender Animation Causes Mesh to stretch in Unity

Hi everyone, I tried importing a model from blender in fbx format to unity and tried to run it's animation. For some reason when the animation runs it causes the mesh to stretch while it's running. When I run it in blender the animation works fine and does not distort/stretch the mesh. Any idea why it is doing this?

 

Setting the blend weights in the quality settings to 4 bones may solve the problem.

 

Where are the quality settings located?

 

Edit> Project Settings> Quality

 

Another possibility that happens frequently:
If you have scaled your model in object mode, you are getting those kind of artifacts. You can solve it by applying the scale and maybe the rotation.

 

Let me add, with ctrl+A in object mode, in case you don't know how to do that.

 

Thanks nipoco! I should have mentioned that.

 

I tried increasing the blend weights and applying the object transform but the mesh is still stretching. I noticed that the stretched bit of the mesh is not moving along with the animation and just sits there in one spot. Any other ideas I could try?

 

Hmm, maybe you have too much bones influence certain vertices. I don't know. If you post the blend I could take a look at it.

 

Can you post the file?

 

I'm going to try re doing the bones and see if that helps. I have a feeling that some of the bones are connected to parts of the mesh that shouldn't.

 

Did you ever fix it? Someone else is having a similar issue, maybe you can help - http://forum.unity3d.com/threads/bu...ng-from-blender-to-unity.428873/#post-2777193

 

Hi, I got same problem as kenaochreous, did you finally found the solution?
I've followed all instructions, but yet none of them all worked. Please help
Thank you

 

Happened to me too in Unity 2019. I guess unity thinks I should rather use a duckel. Just hilarious. Any ideas that the reason is?

 

Were you ever able to solve this? Am having a similar issue and can't find a solution anywhere.

 

This fixed mine too! Ctrl-A, then click Keep Transforms. I re-exported and it worked like a charm.
