auto convex collision doesnt do anything.
I click auto convex collision on my mesh settings.... and it does nothing. Takes a split second and no outcome.. just does nothing. Box simplified works... remove collision works.. all that works... but auto convex does nothing at all..
I imported the model regularly with autogenerate collision set on. I remove collision then try to do auto convex and theres just nothing there.... Any ideas?
Make sure that you have "Enable Collision" Checked for all materials that you want contributing to the collision calculation of Auto Convex Collision.
That setting is checked, by default. I was scared though, and turned it off, because in collision preview mode all materials turned on will display a blue wireframe around the static mesh. ^Technically, this above image has no collision, as collision meshes have either a green or purple wireframe color. I assumed that setting was to use per-vertex collision, but instead it is just to display which meshes will be considered when collision is generated. If "Enable Collision" is off for all materials, the Auto Convex Collision's "apply" button does nothing.

The Auto Convex Collision in the Collision dropdown only opens the Convex Decomposition window (bottom-right by default). You then have to adjust those setting and hit apply.
If I misunderstood what you are see, please let me know.

I was having some issues with no collision happening after converting a group of actors to a new static mesh.
Specifically, I was trying to use Auto Convex Collision and nothing was happening. I saw collision primitives on the mesh but no option to remove them, too. This was even after creating simple box collision primitives and selecting Remove Collision; the new box primitives would disappear but the primitives that existed on the new static mesh after conversion remained.
The solution for me was to do what TJ said: Details > StaticMeshSettings > CollisionComplexity, set to Project Default. Auto Convex Collision worked after that.

I was having this problem too, but this solution didn't work for me. However, there's another UE4 answerhub question that fixed my problem, here:
I've tried about every suggestion that I can and I still get nothing but a progress bar that seems to be hung up. Missing something?
