Question by gabriel-hodali · Jan 09, 2019 at 11:13 AM · meshcollider3d modelimport model

Mesh collider not generated as expected on imported model

Hello

I have a particular problem when generation a meshcollider from a Mesh.

What i did was to create a 3d model in MagicaVoxel and exported it in Unity as a .obj. Then i wanted to have a proper collider for this model. I added a meshCollider and checked/unchecked "Convex" option. I also tried to check "Generate colliders" in the import menu of this model.

in the end i get a meshcollider that is not as expected

alt text

As you can see the model is really basic (looks like a rectangle) but the generated collider doesnt take account of the geometries and i get a wrong collider as a result. Its annoying because i already made all models the same way (for a racing track built block by block) and it could be troublesome to create colliders individually by hand (i have ~100blocks).

Do you have any idea about what i did wrong or if there is a way to generate a precise collider or even multiple colliders (a lot of boxes for example) for each model ? Maybe there is something in MagicaVoxel i can use to take account of the geometry in Unity ?

Thanks in advance !
