Can't see meshcollider green wireframe in scene window

...unless I turn on Convex (Unity 5). Why is that? I understand the purpose of Convex, but why can't I see it in the editor? I'm doing the space shooter tutorial, and on the video he toggles it on and off fine without Convex in whatever version of Unity he's on. Am I doing something wrong or is it a new feature of Unity 5? If I turn off the Mesh Renderer I see nothing, no green wireframe still. I've searched but not getting answer. Thx folks.

EDIT: The Space Shooter Q&A says "Must be set to Convex" but why?

Unity probably likes to make clear wen the collider is working and when not.

 

Forgive the necro on this, but this thread is the top result when searching for "Unity can't see green collider outline", even though this thread isn't 100% related. I'm replying in case others stumble upon this post as well hoping for an answer.

In any case, I was running into this issue, where I couldn't see any green wire outlines for colliders. Turns out I had just unclicked the Gizmos button. Clicking it again restored the green collider outlines.

 

dgoyette, thank you. I ran into this issue when adding the Character Controller component to an object and thought something was wrong with the component. It was indeed the fact that the Gizmos option was unclicked. And this thread was the only relevant links I found in my searching.

 

Thanks Person

 

You're an hero, thank you

 

I don’t believe in necro it doesn’t exist. The internet is the greatest invention in human history and I take full advantage of it.

 

thank u so much!!!!

 

Guy from the future: So...Did anyone find an answer to the original question? This is still the top answer for the original question as well.

 

If you want to see your meshCollider you must first turn off the meshRenderer for that object. You can't see both at the same time.
