How to create custom shaped regions

How do I create a polygon region cause I can't find it, I can only find how to create a box and circular region.

In the scene editor, if you right click the create region symbol it should show the options, box, circle and polygon.

I did that but it only shows box and circle.

That's weird. I was working with polygons yesterday and now I can't find them in regions.

Edit: I think maybe you have to have a polygon shaped actor present in the scene to work with them, or you can create the region yourself in Events.  

I added a polygon shaped actor and it still doesn't appear

Polygon Regions is not supported for iOS.

Polygon Regions is not supported for iOS.

Good to know. That is the other difference in the project I was working with yesterday and the one I was doing today. 

Thanks, I didn't know that

We're very excited about the new engine, which will get rid of most of the platform incompatibilities like this.

There are quite a few exceptions such as this (i.e. no custom polygonal regions on iOS).

Is there a list of these exceptions / differences somewhere?

If not, I think it would be a good idea to formally list them; it's so easy to waste a lot of time on these issues which, if documented could be avoided.

There is on the Pro forums.
