Question by numberkruncher · Feb 28, 2012 at 01:01 PM · collisioncolliderterrainmeshcollider

Problem with colliders going through platforms

I have terrain with a mesh collider (with convex set to false) and a spaceship with a mesh collider (with convex set to true).

There are certain points in the terrain where the spaceship goes through very easily. I do not understand why this is happening because these areas are pretty flat. What should I be looking for?

I am not using any special sort of terrain, just a basic low polygon mesh.

I have the exact same problem when the object I throw is small (or very small).

The problem is because your spaceship uses a mesh colider it will be far more efficient with a box or sphere collider.

I suggest you to user Compound Colliders instead.

I would suggest you use a Box Collider, instead of a mesh Collider. The same thing happened to me, but it worked when I changed it to a Box.

I might have to resort to box colliders, which will be a shame because the inaccuracy of box colliders really notices.
