Question by Shimosama · Jun 13, 2016 at 08:48 PM · blenderrotation axismesh collider

Mesh collider is orthogonal to its object

Today, I created a 3D model, named ufo_catcher, with Blender. After that, I imported its "*.blend" file to Unity as an asset. I dragged it to scene view, and it was displayed correctly. However, when I added Mesh Collider to the object, it was orthogonal to the object. You can see that image below. Why is the mesh's rotation incorrect? I used the mesh that were surrounded by red circle in below image.

Looks like the original mesh is on it's side, but is rotated in the scene. Where in the hierarchy is the collider? You could place the collider on a seperate GameObject and rotate it to match the model.

Although, I imagine you'll want to use the claws as colliders to pick things up, in that case you can scrap the mesh collider and create your own collider tree with boxes.

Sorry for my late reply. Year, you're right. Whene I dropped the object to the scene, its Armature was rotated automatically. So I can correct one, by adding mesh collider to the Armature. Thank you.
