Here is a pic of two nodes that are from me, for you, in 4.4!
It’s for all of you that I send Epic my github pull requests, after all, so that you have even more tools to work with!
**Convert 3D World Location to 2D Screen Space** Convert 3D World Location to Screen Space / HUD (Project 3D point to 2D ) This node has a bool return value to let you know if the 3D point was able to be projected to the screen or not! It could return false in any context where the player controller or the scenefamily could not be successfully obtained. In otherwords, very rarely :) But its worth checking this bool if you are ever getting really odd results and think the node is not working :) The main return value is a Vector2D (fancy way of saying 2D point with x and y member vars) :)
Actually I think this node has been in the engine since 4.3 but I forgot tell you about it.
You can use this node of mine to test if an arbitrary number of points are coplanar!
So basically this mean testing whether any 4 points or more make up a relatively flat surface.
I needed this for the remake of 3ds max I was making in UE4 (I called it UE4 Max, hee hee)
Please note that any 3 points or less are automatically coplanar, ie, you need at least 4 points for this test to be truly valid.
You can control how sensitive my Coplanarity test is!
Use this input to decide how strict the test should be, to get the results you are looking for.
