Model distortion when importing FBX from blender

Hi everyone, I’m new to using both blender AND unreal engine, but I’ve been looking for an answer for a few hours with no luck. I am trying to import a bulbasaur model into Unreal Engine. The model is one that I got from ROEstudios, and when I import it directly to Unreal Engine, all is fine. However, that model has no skeleton. So, in blender, I created a skeletal mesh and a few animations. Everything works fine and looks fine. Here is what it looks like before saving as an fbx file:

However, when I import this model (with animations, skeleton) into Unreal Engine, this is what happens:

I really don’t understand why this is happening and it seems like it only happens to me. I have a feeling I did something incorrectly with my skeletal mesh but I was hoping someone knows what I’m doing wrong.

Hello

So I believe the problem to be related to bone scaling inside of blender. Example would be that you create a single bone then scale it to be the size of the head. Then you further extrude the other bones from that one and thus you get different scaling on the armature/bones. Scale should be 1.0 on all 3 axis.

So when you import into unreal you will get different scale influence on your model at different points thus creating that crazy distorted effect. To make sure your bone/armature scaling is 1.0 in blender select your bone/armature and then push “N” you will see your transform properties on the right.
After that with the bone/armature still selected push “CTRL+A” and apply scale. Normally this would fix it. There may be another problem with your exporting but unless I see the actual BLEND file I won’t know for sure.
