I have recently updated to unit 5.6 and have had an issue where, due to physx removing support for non-convex meshes as triggers, part of my UI no longer works as I was using a mesh to get specific areas of the UI and send event back to unity.
so, as usual with game dev, tying to find solutions to fix issues - I have just spent ages trying to use the mouse pick actions, mostly mouse pick 2d and sprites - long story short - my UI is not on the main camera (I am using an old version of ngui)
So I done a whole load of testing, when the main camera is on and the object is in view of this camera - it works - when I then move it in front of the UI camera it no longer works.
Looking at all the other screen/mouse pick actions they all seem to use the main camera - is it possible to amend them to allow the user to select the camera they want to ray cast from, this would make all those scripts a lot more versatile.
thanks
