I’m new in Unreal Development and I’m working with version 4.11.2.
I have a set of vertices (x, y, z) and I want to draw a line to join the vertices. Note: the first one is also the last one.
How can I do it?
I have tried with Procedural Mesh, but I don’t want to draw a plane or box (I’m not sure what it is), I only want to draw a line.
I’ve been work with Procedural Mesh for a while but I don’t know how to show only a border.
Are you wanting to draw an entire mesh in wireframe basically? or are you wanting larger lines? The PMC only draws triangle meshes, but it is possible to draw a line list, but I’m not sure that’s what you’re wanting?
I want to draw a polygon’s perimeter. Here is an example:
I need to draw the dotted line that it is delimiting Andromeda’s constellation (sorry, I like astronomy and this is the fastest example that I’ve found). Andromeda’s constellation is the white area.
With procedural mesh I can draw that area, but I don’t know how to draw a border or an edge around the mesh, so I think I could do it drawing lines from one vertex to the nearest one.
If you have more questions, please ask me.
Hopefully last question then are you wanting to do this relative to the view, or as a static perimeter around something in effectively 2d? like a skybox or a map? If so then you probably could get by with a linelist which the PMC and CMC doesn’t support but is something I plan on supporting soon in the RMC (link in my footer) This probably isn’t what you’re wanting though if you want to be able to move around an object and see the perimeter.
If you’re wanting something that’s relative to the view kind of like the outline you get in the UE4 editor when you click on an object, then it’s a bit more complicated. I think the common way is to post processes a line based on edge detection in a depth image. I saw this a while back but have never tried to actually do it in UE4 yet.

I have copied a ASpawnVolume class (inherits from ACharacter) from 3rd Person Power-Up Game with C++ (v4.9) video tutorial. It’s a cube with 1600px of side. Inside this cube I’m going to draw the polygon in a 3D space.
I’m sorry, but I’m not very good with English and I’m not sure if I have answered your question.
